User names are meaningless to the filesystem. Numbers matter. Make sure that the name->uid map is identical in all passwd files. In the case below, user1 can't write to /home/user1 because on worker she's got a different uid than on server. Likewise, user3 there appears to own /home/user1 because the uid in question was given to user3. Try the 'id' and 'ls -n' commands to figure it out. Edit passwd and group to fix it.
