Hi, in my test i realize that there is some interaction with mongo registry tickets. When I set default tickets registry or now redis ticket registry there is no problem in logout, but mongo log is set in debug and no messages are displayed.

Maybe i need to put on debug some other module than mongo, I thoght that something is broken when somethis is search for user profile.

Hi,
We encounter a similar problem.

Migration from CAS 5.3 (with Redis) to CAS 6.6 (with Mongo) broke the logout of users authenticated through OIDC.
("class java.lang.String cannot be cast to class org.pac4j.core.profile.UserProfile")

Did you finally succeed in fixing it while still using Mongo?

Thanks,

hi, 

nope, we continue using redis for tickets registry and move to cas 6.6 now, but not try again with mongo due to we are happy with redis performance.

Cheers.

Did you get around this issue. Facing the same problem with Azure AD delegation but I'm using Postgres not Mongo.

Looks like perhaps when user profile is being saved to the session it may end up getting encrypted. On the saveAll, I see user profile in logs as plain text. But when reading user profile from session, debugger looks like it is trying to cast an encrypted string to a UserProfile object.

Thank you for the link. I have reviewed, made slight  modification to use AzureAdProfile.class instead of OidcProfile.class. 

So far looking much better.

I appreciate the assist!
