Yes using dblib I can connect to SQL server but not sybase. 
I see two driver options “MS SQL Server” & "MS SQL Server/Sybase"
What’s the difference between them? Seeing Sybase in driver option I thought it would just work but it doesn’t. I have tried editing freetds config changing tds version to 5.0 both on linux and windows, but not able to make it work.
Can your team provide live support or webex? We can give teamviewer access,if needed. Our app launch is stuck at this point. We are also looking forward to get DF enterprise but can’t wait for its release time.
