infinite redirect loop when auth provider is oidc (after update to 2.160)

hey there,

we just updated to 2.160 today and had to switch back to a version before because:

• jenkins was ending up in a redirect loop
• we use the keycloak plugin (keycloak auth backend)
• also could recreate the same issue with the oidc-auth-plugin (same)
• we deleted cookies on the local browser (same)
• we purged user related sessions in keycloak (same)
• and tested the same in some virgin incognito browser window. (same)
• when switching back to 2.159 all works as expected and before

need some more informations?

could someone look into this?
