Hi, I've migrated about 1700 users from a NT4 server. Everything seems to be exported but many users (not all) are not able to connect to the Samba server. For example : smbclient -L 127.0.0.1 -U arafox password: session setup failed: NT_STATUS_UNSUCCESSFUL I've checked the users entries with "pdbedit -L" and the users who are not able to connect to the server have a entry like that : user:-1:description the users who are able to connect to the server have a positive "uid" Which could be the reasons of this mapping problem ? Thank you, Rapha?l
