Re: Nedd your help to get DBD:Sybase working to connect to SQL Server

And, to add, I’ve recently come across a new Microsoft ODBC driver for Linux.  I haven’t tested it yet, but I can imagine it may address domain logins for example.  It’s on my todo list some day.

(I recently tested a different driver for OS X that allowed domain credentials — very cool…)
