Winbind & Ubuntu 14.04

Recently we decided update our EC2 instances to Ubuntu 14.04.

We had simple Chef recipe based on different walk-through.

Joining to domain with

net ads join dnscreate@AWS.DOMAIN.COM

failed with

kerberos_kinit_password dnscreate@AWS.DOMAIN.COM failed: Cannot contact any KDC for requested realm

 

Same recipe worked with test kitchen. I spent couple days trying to find the reason. It appeared that winbind started to use UDP 88 instead of TCP 88. I didn’t find that in changelog, so beware.
