ODBC connection to microsoft SQL Server works, but I got some problem with OTRS: 1. OTRS look for a table named VALID in my user database (I create a table cloning the one present in the OTRS database) 2. OTRS use a SQL syntax that is not compatible with SQL Server (directive LIMIT), I changed OTRS source to avoid the use of this directive 3. now I'm able to use my SAP BO user table, but I'm not able to give access to customer users to OTRS web site (customer.pl) 4. ODBC give many message (but it work): Subroutine driver redefined at C:/OTRS/Perl/site/lib/DBD/ODBC.pm line 34, <PRODU CT> line 4.
