Okay, so I am doing this for more clarification.
Joining the Linux system to the windows domain using Samba and kerberos.
net ads join -U administrator
Command works fine and the system is part of our domain.
Both commands work fine and bring up the user and group list of the domain.
net ads dns register -P
This command also works fine and the DNS record is created. But only "A" record is created. Corresponding "PTR" record is not created. I dont know why this is happening. But this is happening only with Linux systems.
PTR records for windows systems are created fine without any issues.
Any pointers where the issue might be? Is it to do with windows DNS servers? I am not the administrator for the DNS but can get the access if absolutely needed.
