This document describes the compatability features of the Version 5 server.
|
||
|
|
|
||
|
|
The version 5 server is also capable of responding to requests from
|
||
|
|
clients speaking version 1 of the Prospero Protocol. However, the
|
||
|
|
user should note the following:
|
||
|
|
|
||
|
|
1) The version 1 clients and server never fully implemented the
|
||
|
|
quoting mechanisms that were specified in the Prospero protocol
|
||
|
|
version 1 spec. So, if you use version 5 clients to create links to
|
||
|
|
files with spaces or newlines in their names, or have hostnames with
|
||
|
|
strange characters in their names, or have attributes with strange
|
||
|
|
characters in their names or values, the version 1 clients may not
|
||
|
|
interpret protocol messages about them correctly. There is no fix.
|
||
|
|
If you want to, you can add code to server/dirsrv_v1.c that keeps
|
||
|
|
messages about such objects from being sent; I have not taken the time
|
||
|
|
to do so.
|
||
|
|
|
||
|
|
2) Version 1 Attributes only had type ASCII. Version 5 attributes
|
||
|
|
have type SEQUENCE, and may contain multiple tokens. When speaking to
|
||
|
|
a version 1 protocol server, SEQUENCE attributes are returned with the
|
||
|
|
multiple tokens space-separated. Other types of attributes will be
|
||
|
|
ignored.
|
||
|
|
|
||
|
|
3) It would be best to just forget about using filters with version 1 protocol
|
||
|
|
clients speaking to a version 5 server. Filters have changed
|
||
|
|
radically in version 5, and I have not struggled to make them
|
||
|
|
backwards compatible with version 1 filters.
|
||
|
|
|
||
|
|
4) Access methods have changed radically from version 1 to version 5,
|
||
|
|
as has the syntax of external links. The ACCESS-METHOD attribute is
|
||
|
|
being appropriately munged for the occasion. So you're safe :).
|
||
|
|
|
||
|
|
5) The Prospero version 4 clients and server never fully implemented
|
||
|
|
the V1 protocol's EDIT-LINK-INFO and EDIT-OBJECT-INFO. This remains
|
||
|
|
true; you must use version 5 protocol to edit link and object attributes.
|
||
|
|
|
||
|
|
6) Version 1 protocol clients have no way of sending KERBEROS
|
||
|
|
authentication messages.
