[Samba] Strange user/uid pairs

[rberghmans at arafox.com]

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,
