[cvsnt] unedit -u do nothing

[IAB]

Several files in a directory (and its subdirectories) apparently is being 
edited by a user. Really, this user isn't editing them. I try unedit through 
unedit -u user command. The command output nothing, but the file remain 
"edited" by the user. In files fileattr.xml in cvs's directories in 
repository appears like edited.

What can I do? (delete entries for each exclusive access file in 
fileattr.xml files is a big big task because there are many files)

Thanks in advance.
