Sure, will try to look into it! In the meantime, is there a workaround for this that you can think of? I tried to submit the request as "userA" (as opposed to userA(a)company.com), and then, add the suffix to authenticate the user in the custom LDAP login module. This doesn't work as the JBoss Portal code seems to always pick up the user Principal as "userA(a)company.com". Really need to get past this issue, so any help would be appreciated.
