Hi,
we have set up two more IPA environments. Today we tried to establish the trust to the AD domain but unfortunately we were not successful:
[root@pipag01 ~]# ipa trust-add --type=ad someaddomain.at --admin someadadmin --password Active Directory domain administrator's password: ipa: ERROR: CIFS server communication error: code "3221225653", message "{Device Timeout} The specified I/O operation on %hs was not completed before the time-out period expired." (both may be "None")
What might be the cause? Where should we take a closer look?
If you want to troubleshoot, the official doc has a brand new chapter explaining the sequence establishing a trust, and how to gather debug logs: Troubleshooting setting up a cross-forest trust [1]
Thanks. I will go through that!
The timeout error often happens when the firewall is blocking some of the ports required for AD-IdM communication. You can probably jump directly to this doc section: [2] Ports required for communication between IdM and AD
We could already confirm that there have to be some firewall issues. I will sort that out.
Cheers, Ronald
