Just wondering if someone can point me to the right document.

I've been trying since last week to get the newest Limesurvey build to connect to mssql back end.

I used the pdo_dblib and on the installation database configuration part it won't connect to the mssql server at all.

Using tdsql to the server by ip address and the sa acct I can connect to it. After tsql count about 62 sec then it gave error 20009 - "Adaptive server is unavailable message"
