cannot connect using perl Sybase dbi on Linux to mssql 2008 using a domain user
===

I need to connect to a mssql 2008 R3 database using perl (12.2) on a CentOS box and can do it successfully with a user defined on the database.  However, I need to switch to a domain user and I have not been able to figure out what I need to do to get it to work.  It looks to be correctly setup on the database and here is my connection string:

    my $dsn = ["DBI:Sybase:database=adx;server<server_name>",'<DOMAIN>\\<user>','<password>',{PrintError=>0,RaiseError=>0,AutoCommit=>0}];

Here is the error message:

    database connection failed for DBI:Sybase:database=<db_name>;server=<server_name>
    <DOMAIN>\\<user> : OpenClient message: LAYER = (0) ORIGIN = (0) SEVERITY = (78) NUMBER = (34)
    Server <server_name>, database
    Message String: Adaptive Server connection failed

I believe the tds error (LAYER = (0) ORIGIN = (0) SEVERITY = (78) NUMBER = (34)) is indicating the login failed, but I am sure the password is correct and have tried it directly on a mssql client.  Anyone get this to work?
