[Authentication] Issues with realmd and Fedora 24

[Scott Dowdle]

Greetings,

I am having issues with getting Active Directory authentication working on Fedora 24.  I have a computer science lab of computers and I've used the realm command to join the computers successfully to the domain.  I can pull information about AD users using the id command but I can't login to the computer with AD creditials.  I just get a "System error" error message.

Here's how I did it as the root user:

realm join --user={domainadminaccount} {domain}

It prompts me for a password and I put in my domain admin password and it succeeds.  This is verified by looking up an AD user with the id command:

id {adaccountname}

And it returns all of the AD information on the user.

While I believe AD login for all users is enabled by default, just to be sure I also ran:

realm permit --realm {addomainname} --all

When I try to login from a graphical login manager (lightdm), it just fails to authenticate.  If I try to login from the text console I get, "System error".  Checking the logs, I don't really see any related log entries.  Trying to ssh in, it just get a "closed by remote host" message.

What, pray tell, am I doing wrong?

TYL,
