After configuring IG 2.5 with ADIR as Identity Vault, I could assign the Identity Source and get the users (collect & publish).

Then I defined a global admin from the user source.

But I cannot login with a global administrator defined in ADIR.

I don't see any error in catalina.out nor in osp log.

The only error is on the login screen : login failed, please retry.

Any idea ?
