Thanks Jens, we just verified and can confirm that its using the previous 
session details…

Do you have any idea when this custom cookie storage will make it into the 
release? Next one?

Thanks Christoph

Subject: Re: Authentication issues with Facebook session

1) User logs in via Facebook and uses the Token based authenticator to 
authenticate with the sync gateway.
2) User logs out and logs in with a basic HTTP authenticator

Problem: even though the authenticator is correctly configured and the logic is 
sound, the first authentication attempt happens under the old Facebook user and 
hence the replication is messed up.

It sounds like the Gateway session cookie is still being sent and is overriding 
the basic-auth credentials. (You can verify this by sniffing the HTTP traffic 
using something like Charles.) I would think that the Gateway would check basic 
auth first, but I haven’t looked at that code in a long time. I suggest filing 
a bug against the Gateway.

We then suspected that the CBLManager might be the root cause as this is the 
only process that doesn't get deallocated.

I don’t think so. The CBLManager has nothing to do with replication.

It makes sense for the replicator to clear session-related cookies when it’s 
using basic auth. The problem with that has been that the cookie store 
(NSHTTPCookieStorage) is a global shared by the entire app, so if one 
replicator did this it could destroy state used by another replicator. Pasin 
recently 
implemented<https://github.com/couchbase/couchbase-lite-ios/issues/543> a 
custom per-replicator cookie store that should fix this.
