hi everyone,

i'm new to samba, i did an install and configure of samba 3.0.33 on red
hat 5, security is = ADS.
All seems quite good but... some users are not allowed to connect
("Username.... is invalid on this system" is in log files).

done some debugging with wbinfo:

#wbinfo -u | grep <username OK>
<username OK>

#wbinfo -i <username OK>
blabla correct user name and surname....

#wbinfo -u | grep <username NOT OK>
<username NOT OK>

#wbinfo -i <username NOT OK>
Could not get info for user <username NOT OK>

So samba can find all users, but some of them are "problematic". Basic
AD settings seem identical between user OK and user NOT OK.
What to do?

Thanks in advance!
