umc logon error : Postgresql : nds_nss_GetGroupsbymember

After last upgrade with the ****  issue

I wanted to know of todays update would fix the UMC login.

Well it gives the UMC screen, but I am unable to logon.

When searching for logon failures, I found to check :

systemctl status docker-edirapi.service

systemctl status microfocus-umc-server.service 

and systemctl status postgresql. service

This last one is running, but shows an error :  Postgresql :  nds_nss_GetGroupsbymember ; Failed to init socket, status = 0

Any tips where to look ?
