Unable to connect to postgres using GSSAPI encrypted connection

[Sireax]

I am using kerberos authentication to connect to postgres. In pg_hba.conf there is a separate host type hostgssenc, which enables secure data transport between client and server. If I use this line:

host all all 0.0.0.0/0 gss include_realm=1 krb_realm=DOMAIN1.LOCAL

everything works fine. However, the connection is not secure.
If I change host to hostgssenc, I get this error:

failed to connect to host=postgres user=testuser@DOMAIN1.LOCAL database=vault: server error (FATAL: no pg_hba.conf entry for host "172.18.0.2", user "testuser@DOMAIN1.LOCAL", database "vault", no encryption (SQLSTATE 28000))

If I connect to postgres via psql, the connection becomes secure along with authentication.

I suppose this error may be related to gokrb5 library, but I'm not sure

I don’t understand how this issue has anything to do with pgx(?)

I’m closing this since it does not appear to be related to pgx. Please reopen if you think it is.
