Having trouble with connecting to database via kerberos

Hello!

I wonder if you folks can help me. I am having the hardest time location documentation on, or otherwise figuring out how to connect to a Kerberos-authenticated database using pgAdmin in Amazon RDS.

I can connect to the database just fine with psql + kinit on linux, but the rest of my team is on Windows and pgAdmin.

How, in general, do you connect to a Kerberos-authenticated database from pgAdmin on Windows? I haven't been able to find the answer to this question.

In particular, I am connecting to a 12.3 pgsql database hosted on amazon RDS. No matter what I try, whenever I try to auth via Kerberos, I get this error:

SSPI continuation error: The specified target is unknown or unreachable
(80090303)

If I connect using a local pg user, the connection succeeds.
If I connect using kinit + psql on linux, the connection succeeds.
If I connect using the correct host endpoint, I get the error above.
If I connect using the AWS alternative method described here[1] of connecting to <endpoint>.<aws-ad-domain>, I *still* get the error above.

Is there anyone who can help?
