Hi folks,

Further to Ricky's reply, I've had a look at the xattr's and acl's of 
the profiles folder after running an rsync with the -p, -A and -X switches.

Checking the permissions on both servers they appear to be the same, the 
have the same owner and groups.  Having checked the acls and xattrs they 
match on both servers.

I've restarted Samba on the second server after rsyncing to it and 
checked the permissions again but I'm still getting the incorrect 
permissions :-(

I wondered if there might be anywhere I can check where the permissions 
might be stored?
