Univention management console 4.3 error

UCS - Univention Corporate Server
#1

I had installed UCS 4.3 and after upload UCS license and rebooting server cant login and saw this error

Internal server error: The service is temporarily not available.
Cannot connect to the LDAP service.
The following steps can help to solve this problem:

  • Check if enough hard disk space and free RAM is available on this server or free some resources
  • Restart the LDAP service on the domain controller master either via “service slapd restart” on command line or with the UMC module “System services”
Fresh Univention VM, Domain Controller, "Cannot connect to the LDAP service"

Hey,

sounds like your LDAP server isn’t running. Please log in via ssh & show the output of systemctl status slapd.service

Then try starting via systemctl start slapd.service and see if that makes a difference for the UMC.

Kind regards,
