We are facing connectivity issue while trying to access Sybase database from a Perl module. We are trying to access remote Sybase database from a Perl script on a linux server. We have installed Sybase OCS 16.0.0 and DBD-Sybase-1.15.20 on the Linux server Below is the code snippet we are using to connect to Sybase database 
Code:

$dbh_auto = DBI->connect('dbi:Sybase:server=XXXXXX;database=XXXXXX',$A
+PP_SYB_USER,$APP_SYB_PASS);

Error :

DBI connect('server=XXXXXXX;database=XXXXX','xxxxx',...) failed: Serve
+r message number=4002 severity=14 state=1 line=0 server=XXXXXX text=L
+ogin failed.
OpenClient message: LAYER = (4) ORIGIN = (1) SEVERITY = (4) NUMBER = (
+44)
Server lon_gbe_sql_dev2, database
Message String: ct_connect(): protocol specific layer: external error:
+ The attempt to connect to the server failed.

We were able to access the database using iSQL and SQL developer with same credentials.
