Dear Sir or Madam,
my college configured an external trust for our existing Active Directory. We have joined our Linux Server using realmd and aren't able resolving any user IDs from the new trusted domain using sssd. I am in fact able to get a Kerberos Ticket with credentials of the trusted domain. Is this a known issue? Please let me know if I am able to provide any futher information. Logfiles are attached to this mail.
System requirements: - centos7 with sssd 1.12.2-58 joined to active directory domain 'content.zone'. 'content.zone' in turn trusts (one-way, external) the domain 'oew.de'.
Symptoms: - 'id user@oew.de' gives the error message ' GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Server not found in Kerberos database)]' - resolving user@content.zone works without a hitch.
Error Message: (Thu Jul 30 09:07:28 2015) [sssd[be[content.zone]]] [sasl_bind_send] (0x0080): Extended failure message: [SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Server not found in Kerberos database)]
How to reproduce: sudo realm join --user="administrator" --computer-ou=OU=Computers,OU=CAP,DC=content,DC=zone content.zone sudo systemctl stop sssd; sudo rm -rf /var/lib/sss/db/*; sudo systemctl start sssd id administrator@oew.de
