Error "SAML response reported an IdP error" after Login

Hello all,

we have some users who currently can't log in to certain systems at all (for example Moodle). In the SP log I find the following entry:

2023-06-05 23:22:00 WARN Shibboleth.SSO.SAML2 [147] [default]: error processing incoming assertion: SAML response reported an IdP error.

I already looked into the IdP logs and I don't see any error there. It also unfortunately affects only a certain amount of users and that permanently, the error can be reproduced from the user, but not from my side. Anyone here have any idea where else I should look? Is a DEBUG output maybe helpful?
