BI 4.1 SP7 & LDAP/AD Trusted authentication

Hello,

We facing a problem with trusted authentication in BI 4.1 SP7 with user mapped from LDAP.

We have 2 AIX plateforms 1 Bo tiers and 1 Web tiers (Tomcat 7).

We can manually connect users LDAP.

We activated sso with trusted authetication. When we test with Query_STRING like :http://server:8080/BOE/BI?user=Administrator, it works.

But when we try the same method with LDAP user, we facing the issue:"user must have at least one alias (FWB 00010)".

Our licences have 2400 named user and the plateform have for the moment, >100 users.

Does someone have an idea to resolve our issue?

Thanks in advance
