Boa noite,

Tenho um Ubuntu Server 13.4 autenticação no Active Directory e a princípio autentica, sem problemas. Porém em um determinado momento, a conexão cai. Ao que me parece pode ser problemas no winbind, mas não tenho certeza.

Nos comandos wbinfo -t e wbinfo -u ele responde de forma positiva. Nos logs do squid ele começa a dar ACCESS DENIED e nada a mais, então verifiquei os logs do winbind.

Segue:

Percebo que ele perde a conectividade com o winbind durante um tempo curto. (request interface version) e (request netbios name)

Percebo também que ao ocorrer este problema com o winbind, quando digito o comando net ads info, fica da seguinte forma:

root@matrix:~# net ads info
ads_connect: No logon servers
ads_connect: No logon servers
Didn't find the ldap server!


Como posso resolver isso?

Abs.
