I am having a hard time adding a CentOS 7 machine to my domain (Active Directory 2012 running in Windows 2008 mode). I am using
realmd to join the machine to the domain. Here is what I have checked so far:
- I have basic network connectivity - I can ping all of my DCs
- DNS is working - I am able to resolve LDAP and Kerberos SRV records
- I am able to connect to LDAP and LDAPS ports on my DC (tested using
telnet- connection opens). I have even tried disabling the firewall completely on a DC to try and rule out the traffic being blocked
- when I do the command
realm discover domain.comit outputs my domain information
When I attempt to join the domain, I get an error:
kinit succeeded but ads_sasl_spnego_krb5_bind failed: Cannot contact any KDC for requested realm
I'd appreciate any help that can be offered. I have no idea what is going on, and I've searched everywhere and damn near have read the entire
sssd webpages to try and figure out what is wrong. Thanks!
So I checked my Active Directory, and it adds the computer to the domain, yet it tells me that it fails? There is a computer object there now, but I can't do anything in terms of authentication.
I am running CentOS 7 Minimal Install
