so why do I get a password error when i try to connect 2 users over VPN from the same machine to the same host with the following settings in pg_dba.conf - how to find the issue
( user1:user1pwd@<vpnip/database> & user2:user2pwd@<vpnip/database> )
# IPv4 external connections thru VPN
#TYPE DATABASE USER ADDRESS METHOD
host all all <ip> scram-sha-256
host all all <ip> scram-sha-256
and whats the best option keeping security in mind
regards
Sanjay

While correctness and security always needs to be evaluated from the specific
needs of an installation, the odds are pretty good that "No" is the correct
answer here. To quote the documentation on the "trust" setting:
"Allow the connection unconditionally. This method allows anyone that
can connect to the PostgreSQL database server to login as any
PostgreSQL user they wish, without the need for a password or any other
authentication."
I would recommend immediately reverting back to the scram-sha-256 setting and
figuring out why you were unable to login.
