username case-sensitively when looking up the user info in pg_authid, and if the user logged on to Windows with a name
differingin case from what the database thinks it is, authentication fails. Npgsql sending it always in lower case is
preciselywhat I landed on as a workaround (basically overriding libpq's automatic user name detection in the ODBC
connectionstring by appending a UID option).
The message I get in the log is "provided user name
(bcrowell@REALM.COM) and authenticated username (BCrowell@REALM.COM)
do not match," so it looks like I have to teach Npgsql to match
whatever Windows is sending in GSSAPI. That, or teach Postgres how to
lowercase the name on arrival.
What did you do to get around this?
