[Samba] 3.5.6 to 3.6.6: session setup failed

[Thiago Parolin]

Hi,
I think that someone has the solution for my problem! ;)
After i did the upgrade process in a samba server, from debian squeeze to
wheezy, the new samba version (3.6.6) is not working.
Searching on web, there are many causes for this error, and i dont know
what is mine.
I can't connect with smbclient -L host -U ldapuser, that give me error
"session setup failed: NT_STATUS_UNSUCCESSFUL"


How can i fix this?
