[midPoint] "Unknown" username in SAML

[Zico]

Hello again!

I am trying to connect Midpoint authentication with Gluu Server SAML (
Shibboleth ).
I think I am almost there as now my "Midpoint" is forwarding to Gluu Server
for authentication.
After authentication, I am jumping into Midpoint again with below error.

I know I have two users ( one: administrator and another one: mohib ) in
Midpoint and both are SuperUser of course.

I can't understand why Midpoint unable to recognize UID I am forwarding
from Gluu Server.
In Gluu Server SAML assertion, I see that I am sending proper attributes (
including UID / Username ).

Any hint or suggestion please?

midpoint.log saying something like this:
