Changing from SQL Authentication to Windows Authentication

Hello,

We currently have an odbc call configured (tcl script using odbc driver) on an AIX platform.  The login currently uses “SQL Authentication”.  Works fine.  But we want to change it to use “Windows Authentication” and we have been unsuccessful.  I’m assuming that the odbc driver (and odbc.ini) file utilize “SQL Authentication” by default, since it’s currently working, and I don’t see anywhere this is specifically specified.  I am wondering if there is a config setting that could be added/changed (maybe in the odbc.ini file) which would allow us to utilize “Windows Authentication”. ?

Anyone? …   Anyone? …  

Bueller?
