Hello,

the SAML login on UMC is not working anymore.

I don’t now the problem already exist because I haven’t used it for a long time.

Not long ago I created new certificates for the UCS systems. Maybe this is the source of the problem. But I don’t changed the UCS CA and also not the ucs-sso certificate.

Backtrace:
