I'm installing OTRS Help Desk for our organization. We're installing the application on a CentOS server but would like to connect to a Microsft SQL Server database. However, I was not able to install the ODBC driver on the OTRS server. MS SQL Server is also not an option in my web installation of OTRS (I have MySQL, PostgreSQL, and Oracle). Because I know OTRS can be installed on Windows, I'm wondering if for it to be compatible with MS SQL Server, it must be installed on Windows. If not, how do I get MS SQL as an option for my database?
