[otrs] customer in ext. MSSQL DB

Hi all, I have a general question in regards of the use of an external MSSQL DB. We are hosting user data on this DB, which partially is interesting to have in otrs. So what I basically want is a one way thing, let otrs connect to that DB and leech some records. I don't need to write into that DB, that's handled from somewhere else. All the rest (tickets, queues etc.) is stored in the otrs machine/psql db. Does anyone have experience with this that he'd like to share? -- * Julian
