Hi Guys, I work in a business that is predominantly WINTEL based, but i've done some work on linux and also just completed the RH199 course so I'm now i'm looking to put all that knowledge to use. Just wanted to know if my thinking is correct here. Trying to offer a method for our linux boxes to A) authenticate using our AD infrastructure. B) authenticate predetermined SMB mounts on a Windows File Server using AD creds. So for A) we used authconfig on RHEL systems. Unfortunately, we use predominantly debian and ubuntu servers, and this is not available on RHEL. Looking further into it i've been led down the realmd path using sssd and krb5. Unfortunately i've hit a snag. When using: Code: realm discover domain.example.local I get a resolve timeout on _ldap._tcp.domain.example.local and it doesn't allow me to join the realm. Doing a: Code: host -t SRV _ldap._tcp.domain.example.local Returns entries for all of our DC's, but still get timeouts for the realm discover. Another interesting thing to note is that it doesn't even discover any of the services available. For B) once i do get realmd working and sssd for authentication, i should be able to use sec=krb5p/krb5i on the fstab entry correct, or should i use smbcreds file and use a "service" account to map this predetermined account?
