I have configured winbind(3.26) on RHEL 4 host and initially everything seems to be working. But the authentication stopped working after sometime. When wbinfo -u is run, then again it starts working. Seems something is timing out. And trusted domain is set to no, but still the wbinfo shows the trusted info. Any ideas? [global] workgroup = DOM1 realm = DOM1.EXAMPLE.NET security = ADS allow trusted domains = No password server = PDC.DOM1.EXAMPLE.NET lanman auth = No ntlm auth = No client NTLMv2 auth = Yes client lanman auth = No client plaintext auth = No log file = /var/log/winbind ldap ssl = no idmap backend = ad template shell = /bin/bash winbind separator = + winbind use default domain = Yes winbind nss info = template, sfu Cheers, LA
