Hello all, apologies for this - I'm having an issue where I have a single Kerberos realm (published as the RADIUS realm) but multiple AD containers behind that, within which the users sit. The RADIUS/Kerberos server is joined to the domain and authentication via ntlm_auth works for both containers (if one specifies the container explicitly) # ntlm_auth --username=testusera --domain=a.example.com Password: NT_STATUS_OK: The operation completed successfully. (0x0) # ntlm_auth --username=testuserb --domain=b.example.com Password: NT_STATUS_OK: The operation completed successfully. (0x0) # So: Kerberos/RADIUS realm = example.com; users are in containers a.example.com & b.example.com Can I use the krb5.conf to handle the users as "user@example.com" and automatically have it try both containers (i.e. a.example.com & b.example.com)? I'm surmising that I need to do this in the realms and/or domain_realm sections - but the documentation isn't making a whole lot of sense to me at this stage (could be related to a caffeine deficit) Thanks in advance Jason ******************************************************************************************************************** This message may contain confidential information.
