HP CIFS Client A.02.02 Release Notes, April 2006

Known Problems and Workarounds
This section provides a list of known problems and workrounds as known to HP at time of publication.
For the HP CIFS Client
• Byte range lock is not supported
Byte range locks over a cifs mount are not supported. Calls to lockf(1) and fcntl(1) over a
cifsmount will fail. Support for byte range locks will be added in a future release of the HP CIFS Client.
• Removing a Directory and its Contents
Removing a directory and its contents in one step using the command, rm -rf <directory>, may
fail on directories located on a cifsmount. If the directory contains ~30 or more files, only part of
the directory contents will be removed and the directory itself will remain since its contents have not
been removed.
A workaround is to remove the directory and its contents in two steps as follows:
1. rm —rf <dir>/*
2. rmdir <dir>
• Moving files and/or directories over DFS links
Attempting to move a file or directory over a DFS link directory is not supported and will result in
“rename: Permission denied” error.
A workwaround is to first copy the file to the DFS link directory and then remove the original file as
follows
1. cp moveFile dfs_link_directory/
2. rm moveFile
• NTLMv2 Authentication with HP CIFS Servers
If the CIFS Client is configured to use NTLMv2 authentication, and the user attempts to login via
cifsmount or cifslogin to an HP CIFS Server that is a member of a domain, then the domain
must be specified, in UPPERCASE, either on the command-line, via the “-D domain” option, or in the
configuration file.
For PAM NTLM
The passwd(1) program may not return any message (Success or Failure) in some cases. For example, if
the user tries to change his password when the "user cannot change password" option is set on the NT
server, the passwd command does not return a message. In such cases, check the return value of the
passwd command (passwd returns zero for success) and the syslog file (/var/adm/syslog/syslog.log).
