After we installed a new set of IPA servers for prod, and joined AD using username and password to have AD create a correct suffix routing everythin seems to work, and the suffix routing is created correctly on AD. 

However, trying to SSH from Windows using Putty and kerberos fails: 

Putty log shows: 
Event Log: GSSAPI authentication initialisation failed 
Event Log: No authority could be contacted for authentication.The domain name of the authenticating party could be wrong, the domain could be unreachable, or there might have been a trust relationship failure. 

DNS is on AD (manually added, and IPA have no DNS installed. 

Kerberos DNS is correct:

Klist on Windows shows I have a TGT for the LX domain (but only a TGT), sorry for the danish.
