bad password error -951 in Server Studio

This seems straight forward... hopefully someone knows a quick answer. IDS 11.7 FC5 Red Hat Enterprise Server release 6.3 (Santiago) Trying to connect through Server Studio. Testing the database connection gets the following errors: 10:05:06 Get Shadow Password for user [lgustin] failed! 10:05:06 Check for password aging/account lock-out. 10:05:06 listener-thread: err = -951: oserr = 0: errstr = lgustin@111.111.111.111: Incorrect password or user lgustin@111.111.111.111 is not known on the database server. The test for the ssh connection goes through fine. Which means the username and password really are correct. I'm thinking it has to do with access to the /etc/shadow file which has permissions 000 (and needs to stay that way). Any ideas? Thanks Laurie
