Good day!
I am running UCS 4.4-5 errata737 on ProxMox 6.2-11 using a raw img, 2 kvm cpu’s and 4g mem. I have 1 UCS master DNS server, 1 USC backup server, and one UCS slave running apps like owncloud, colabora, CRM… Everything was working fine then randomly things started to break when I ran the diagnostic tools. This is the error I am seeing:
Critical: KDC service check
ph
TEST AGAIN ADD LO TO SAMBA/INTERFACES RESET KERBEROS/KDC TO 127.0.0.1
Problem: SAML certificate verification failed!
Traceback (most recent call last):

I have combed the Univention help forums to no avail. This is the second time a stable UCS setup has crashed on me in 7 months with out any direct intervention on my part, meaning tinkering with LDAP, Kerberos, Samba… Ect… I have installed apps such as owncloud, let’s encrypt, self service portal… But nothing was installed or removed directly before this issue started.
Updating to 4.4-6 does not fix the issue.
Thoughts?
