The Sybase ASE driver only seems to allow DB authentication..
This is also causing us some problems with rolling it out to a wider set of users, as we need a single sign on option (e.g. windows authentication) to help reduce the barriers to seting up users and users getting and obtaining a DB password.
Tableau - are there any plans to include windows authentication for the Sybase driver, in a similar fashion to what the SQL server driver allows? (both DB plateforms support windows authentication)
Yes, there are plans to add single sign-on support for Sybase. In fact, we're working on it now and are planning to add this support in a coming release. We will post details here as soon as it's available for testing. Tableau Pre-Release Programs | Tableau Software
