You're right, that's the telltale message for a failed domain login.  Is
there any chance that $app_server is empty, or contains a '\' character?  In
that event, FreeTDS would attempt a domain login.  I'm not sure the "tds
server/domain login" entries have any effect anymore (they might).  

(Memo to file: We should note the type of login in the log when we record
the connection attempt.)

I doubt LD_LIBRARY_PATH is the issue.  If you doubt your freetds.conf is
being consulted, the TDSDUMPCONFIG variable should clear that up.

I don't think that connect() call is right.  Are you using DBI or Sybperl?  

If DBI, you need "use DBD::Sybase" (and will use FreeTDS's ct-lib), and
would connect with:

        $dbh = DBI->connect("dbi:Sybase:server=$app_server", $app_user,
$app_passwd);

If Sybperl, you can use Sybase::DBlib, but your database handle would be
constructed:

        $dbh = new Sybase::DBlib $app_user, $app_passwd, $app_server,
'test_app';

Cf. "perldoc DBD::Sybase" and "perldoc Sybase::DBlib" for details.   ;-)

Perhaps by bolting things together incorrectly, you managed to pass a null
username to the FreeTDS login function?
