Had to attempt to login multiple times before login to AIX server was successful. Sometime the login to account would succeed and sometimes with the same account right after success it would fail.
The mapped_user table had some incorrect data in it.
1) edit /etc/user-map file
deleted duplicated enteries
2) /opt/quest/libexec/vas/vasd/vas_muupd -d -g5 --unmap-all
3) /opt/quest/libexec/vas/vasd/vas_muupd -d -g5 -f
Command to get a list of mapped user that are in the database file:
/opt/quest/libexec/vas/sqlite3 /var/opt/quest/vas/vasd/vas_ident.vdb "SELECT * FROM mapped_user"
