That's not a good idea, certainly not right away, and you're almost guaranteed to break it doing that. We do not at all advise that in general, quite the opposite.

I've never seen such an error, but I cannot speak to Tomcat.

If you're planning to proxy to Azure, I wouldn't waste much time on LDAP, and you could have just swapped in the RemoteUser support much more easily as a stepping stone, but I don't think that's anything to do with LDAP, or even the IdP at all, seems more like a Tomcat problem.
