[Cognos 11] Error Auth server when open project

[banghn]

Fist, I'm sorry I do not know what to put this topic on box.

I'm working on Cognos Analytic 11.0.6 version. I just started a few weeks ago.
In Cognos Cofiguration Server, I created Auth with LDAP Server and I test ok with browser.

But in Cognos Framework Manager, when I open or create Project. It appeared error auth (Maybe)


Who can help me resolved this problem. Many thanks.
