Maybe you want to look at LIMITATIONS in README. Some might consider
them to be bugs.

But there are really problems that might be fixed in the future.

Invalid directory timestamps: 
I did not yet find out how to get valid timestamps for directories
from a NetWare server. So I simply return 0, which means 01.01.70. If
anybody knows how to get these values, please mail
lendecke@namu01.gwdg.de.

'df' returns 0:
Free disk space is distributed among the volumes in NetWare. df is
only able to report one number per mounted filesystem. As connections
are quite expensive for NetWare (with lwared that might change ...), I
rejected the alternative to mount only a single volume for a unix
mount point. So I simply return 0.
