Hello all, Help!! Am running Unix 2.4 and Samba allowing windows clients to map the Unix server. Some users have been unable to connect to mapped drives and having looked at the logs I see the message: Unable to initgroup! this is probably a problem with the account nobody This message appears in all the user logs, however, only some users have the problem of connecting. I have looked at the smb.conf file and cannot seemingly find any errors, there again, I am not to sure of what I am looking for or am I looking in the right place. I also noticed that all the samba directories and files have the permission and ownerships set to '770 guest physiol', physiol being the group. In the smb.conf, masks are set to '775', which has confused me, as the problem affects some and not others. This setup is a legacy of a previous administrator which has been handed over to me. I have very little knowledge of Samba. Can anyone point me in the right direction?
