+The build and install rules install the web UI binary, Perl helpers, configuration template, static assets, systemd unit, and PAM file as part of the integrated installation target.

 ## Architecture overview

-SMArT consists of two main parts:
+SMArT consists of three main pieces:

-1. **Perl-based application logic** for configuration pages and helper scripts
-2. **`nwwebui` service** as the web frontend that exposes the application over HTTP and HTTPS
+1. **`nwwebui`** – a dedicated HTTP/HTTPS frontend service
+2. **Perl helper scripts** – request routing, configuration pages, bindery operations, validation, and service control
+3. **Small native helpers** – PAM login checking and optional user enumeration helpers

-The current implementation adds a dedicated `nwwebui` service that can serve the application directly over:
+The `nwwebui` service can expose the UI over:

 - **HTTP on port 9080**
 - **HTTPS on port 9443**

-The service supports TLS via OpenSSL and can run both listeners in parallel. HTTPS is the preferred mode because authentication happens more securely over an encrypted connection, while plain HTTP may still be useful for testing or trusted internal environments.
+Both listeners can run in parallel. HTTPS is recommended for real deployments because the login form transmits credentials. Plain HTTP is still useful for local testing or trusted internal environments.

-## Security model
+## Major features

-SMArT uses PAM-based authentication through the `check_login` helper. The supplied PAM policy is a standard `pam_unix` stack for authentication, account, password, and session handling. During installation with **MARS_NWE**, this file is installed automatically as:
+### HTML login, sessions, and logout

- `/etc/pam.d/smart`
+SMArT provides a form-based login page, session cookies, and a logout action. Static assets such as the SMArT logo are served before authentication so the login page can render correctly.

-That means no manual PAM file deployment is normally required when SMArT is installed through the integrated `mars_nwe` package or release.
+Runtime session files are stored under the WebUI runtime directory, typically:
+
+```text
+/run/mars-nwe-webui
+```
+
+### PAM authentication with administrator group restriction
+
+Authentication is performed through the PAM service `smart` using the `check_login` helper. In addition to a successful PAM login, the user must be a member of the configured Unix administrator group.
+
+The administrator group is configured at build time through the main `mars_nwe` CMake project:
+
+```bash
+cmake -DMARS_NWE_SMART_ADMIN_GROUP=root ...
+```
+
+The default is `root` to preserve the traditional behavior on existing systems. On normal Unix systems the `root` user has primary group `root`, so root can still log in. For delegated administration, build with a dedicated group instead:
+
+```bash
+cmake -DMARS_NWE_SMART_ADMIN_GROUP=nwadmin ...
+groupadd nwadmin
+usermod -aG nwadmin mario
+```
+
+After installation the effective setting appears in `smart.conf` as:
+
+```perl
+$smart_admin_group = 'root';
+```
+
+or, for a delegated build:
+
+```perl
+$smart_admin_group = 'nwadmin';
+```
+
+### Service control page
+
+The start page includes controls for the configured MARS_NWE service:
+
+- start
+- stop
+- restart
+- status
+
+The service name is supplied by the build configuration and can be overridden in `smart.conf`:
+
+```perl
+$mars_nwe_service = 'mars-nwe-serv.service';
+$smart_systemctl_path = '/usr/bin/systemctl';
+```
+
+### Runtime information page
+
+The start page shows the important runtime paths generated by CMake, including:
+
+- main MARS_NWE configuration file
+- SMArT configuration file
+- WebUI helper/script directory
+- MARS_NWE service unit name
+- `systemctl` executable
+
+This helps diagnose packaging or installation path issues without searching through generated files.
+
+### Configuration editors and advanced sections
+
+The main menu contains the commonly used configuration areas and advanced sections. Advanced pages are shown only when the selected section is opened, which keeps the menu usable while still exposing low-level MARS_NWE options.
+
+Current sections include, among others:
+
+- setup first
+- MARS_NWE service
+- general settings
+- directories
+- precompiled/path settings
+- security
+- user configuration
+- volumes
+- devices
+- logging
+- stations/access control
+- users
+- groups
+- print queues
+
+### Import helpers
+
+SMArT can prefill or discover host-side data for common configuration tasks:
+
+- local mount points for volume creation
+- Unix users for MARS_NWE user mapping
+- CUPS printers for print queue command generation
+- IPX interfaces for device configuration
+
+These helpers are meant to reduce manual typing while still leaving the final configuration under administrator control.
+
+### Validation and error pages
+
+The apply path validates common input before writing configuration or changing bindery data. Invalid values are shown on a dedicated validation page instead of failing silently or returning an empty HTTP response.
+
+Validation currently covers areas such as:
+
+- volume names and Unix paths
+- device/network parameters
+- print queue names, print commands, and spool directories
+- user names and group names
+- invalid bindery characters
+
+### Bindery command handling
+
+Bindery operations are executed through checked helper functions instead of silent `system()` calls. The WebUI logs command start, command success, command failure, and relevant output.
+
+Commands such as `nwbocreate`, `nwbprm`, and `nwborm` are handled through `run_bindery_cmd()`. Pipe-style `nwbpset` operations are handled through `run_bindery_pipe()` using a temporary input file and checked return code.
+
+This improves diagnostics for user, group, and print queue operations. The browser receives a structured error page when a bindery command fails.
+
+### Bindery success pages
+
+After successful user, group, or print queue changes, SMArT can show a result page with the number of successful bindery commands. This makes bindery changes visible to the administrator and avoids silent redirects after complex operations.
+
+### Optional Unix user mapping updates
+
+Existing MARS_NWE users no longer have their `UNIX_USER` mapping removed unless the administrator explicitly requests a mapping change. This prevents accidental loss of Unix user assignments when only editing full name, password, or group membership.
+
+## Logging
+
+SMArT has two relevant log streams:
+
+- the `nwwebui` service log
+- the Perl frontend log, normally `smart.log`
+
+Typical paths:
+
+```text
+/var/log/mars_nwe/nwwebui.log
+/var/log/mars_nwe/smart.log
+```
+
+### Perl frontend log level
+
+The Perl frontend log level is configured in `smart.conf`:
+
+```perl
+# SMArT Perl logging verbosity.
+# Values: error, warning, info, debug, trace
+# Default: info
+$smart_debug_level = 'info';
+```
+
+Supported values, from quiet to verbose:
+
+- `error` – only real errors that abort or fail an operation
+- `warning` – errors and warnings about unusual but non-fatal situations
+- `info` – normal operational messages, command start/finish, default
+- `debug` – additional diagnostic information for troubleshooting
+- `trace` – very verbose step-by-step traces, including bindery pipe payloads
+
+Use `trace` only while debugging a concrete problem. It may include submitted bindery payload data and can produce a lot of log output. After debugging, switch back to `info`.
+
+### `nwwebui` service log level
+
+The `nwwebui` service has its own numeric log level:
+
+```perl
+$nw_log_level  = 'info';
+```
+
+Typical meanings:
+
+- `0` = errors only
+- `1` = informational messages
+- `2` = debug output

-## `smart.conf` settings explained
+### Print queue test action

-### UI colors
+The print queue page can submit a small test job to an existing MARS_NWE queue
+through the ncpfs `nprint` tool.  This verifies the queue through the NetWare
+print-queue path instead of only checking the local Unix/CUPS command.

-These variables define the default SMArT page colors:
+The helper path can be adjusted in `smart.conf`:

- `$COLOR_BACK` – page background
- `$COLOR_HEAD_BACK` / `$COLOR_HEAD_FORE` – main section header colors
- `$COLOR_SUBH_BACK` / `$COLOR_SUBH_FORE` – subsection header colors
- `$COLOR_TEXT_BACK` / `$COLOR_TEXT_FORE` – regular content row colors
+```perl
+$smart_nprint_path = '/usr/bin/nprint';
+```

-### Main MARS_NWE configuration
+## Recent SMArT WebUI features

- `$mars_config` – path to the main `nwserv.conf` file that SMArT reads and updates
- `$nonroot_user` – unprivileged user account used when SMArT drops privileges
- `$smart_compact_nwservconf` – controls how `nwserv.conf` is written back:
-  - `0` keeps comments, spacing, and the original structure as much as possible
-  - `1` writes a more compact version without the original long comment layout
+The current WebUI includes several usability and safety improvements:

-### SMArT internal file layout
+- HTML login, session cookies and logout handling
+- static asset serving before login, so the login page can load the SMArT logo
+- service-control pages for start, stop, restart and status actions

- `$nw_bind_ip` – bind address for HTTP and HTTPS listeners, for example `0.0.0.0` for all IPv4 interfaces or `127.0.0.1` for localhost-only access
- `$nw_log_level` – service log verbosity:
-  - `0` = errors only
-  - `1` = informational messages
-  - `2` = debug output
- `$nw_daemonize` – whether `nwwebui` detaches into the background
- `$nw_pid_file` – location of the PID file
- `$nw_log_file` – log file written by `nwwebui`
- `$nw_ssl_enable` – enables or disables HTTPS support
- `$nw_http_port` – HTTP listener port; set to `0` to disable plain HTTP
- `$nw_https_port` – HTTPS listener port; set to `0` to disable HTTPS

-The current code and template show that:
+Useful build-time settings include:

- `nwwebui` listens on `9080` for HTTP by default
- `9443` is used for HTTPS
- the log file can be configured with `$nw_log_file`
- the log path can also be overridden at runtime with `-l`
+```bash
+cmake -DMARS_NWE_SMART_ADMIN_GROUP=root ...
+cmake -DMARS_NWE_SMART_ADMIN_GROUP=nwadmin ...
+cmake -DMARS_NWE_SYSTEMD_SERVICE=mars-nwe-serv.service ...
+```

-Because passwords may be transmitted during login, HTTPS is the recommended way to access the interface.
+The administrator group defaults to `root` for compatibility. Use a dedicated group such as `nwadmin` when non-root administrators should be allowed to access the WebUI.

 ## Starting the service

-Depending on the installation method, `nwwebui` can be started either via **systemd** or directly from the **command line**. The build system installs a `mars-nwe-webui.service` unit when systemd support is enabled.

-## Build and installation notes
+## Native helper logging

-This repository is built as part of the main `mars_nwe` build. The build system:
+The native helper programs `check_login` and `smart_userlist` read their log
+destination and verbosity from `smart.conf` when called by the WebUI.

- generates `smart.conf` from the template
- generates the `smart` launcher script
- builds `nwwebui`
- builds `check_login`
- installs the PAM file and static UI assets
+They use the same Perl frontend settings:

-Because this repository is integrated as a Git submodule in `mars_nwe`, end users normally consume it through the main `mars_nwe` source tree and release packages rather than using it as a standalone project.
+```perl
+$smart_log_path = '/var/log/mars_nwe/smart.log';
+$smart_debug_level = 'info';
+```
+
+The generated `config.h` also provides fallback defaults for these values, so
+the helpers can still write useful diagnostics when they are executed manually
+or before `smart.conf` could be loaded.
+
+`check_login` logs authentication and authorization results, but never logs the
+submitted password.  `smart_userlist` keeps its tab-separated user-list output
+on stdout unchanged and writes diagnostics only to the configured log file.
+
+## Unix user discovery helper
+
+The WebUI user editor can assign a MARS_NWE bindery user to a local Unix user.
+For this selector, SMArT uses the native `smart_userlist` helper.
+
+`smart_userlist` enumerates local users through the system user database instead
+of relying on fragile parsing in the web page itself.  This keeps the optional
+Unix-user mapping UI usable even when the available users come from NSS-backed
+sources such as local files, LDAP, SSSD or similar site-specific setups.
+
+The helper is installed together with the other SMArT native tools and is
+normally referenced from `smart.conf` as:
+
+```perl
+$smart_userlist_path = '/usr/libexec/mars_nwe/smart_userlist';
+```
+
+If the path is not set explicitly, SMArT falls back to the standard libexec
+location generated by the build system.

+# This controls log messages written by the Perl CGI-style helper scripts
+# such as apply.pl.  The messages are written to the SMArT log file configured
+# for the WebUI, normally:
+#
+#   /var/log/mars_nwe/smart.log
+#
+# Supported values, from quiet to verbose:
+#
+#   error   - only real errors that abort or fail an operation
+#   warning - errors and warnings about unusual but non-fatal situations
+#   info    - normal operational messages, command start/finish, default
+#   debug   - additional diagnostic information for troubleshooting
+#   trace   - very verbose step-by-step traces, including bindery pipe payloads
+#
+# Recommended setting for normal operation:
+#
+#   $smart_debug_level = 'info';
+#
+# Use 'trace' only while debugging a concrete problem.  Trace logging may
+# include submitted bindery payload data and can produce a lot of log output.
+# After debugging, switch back to 'info'.
+$smart_debug_level = 'info';
