[mapserver-users] PostgreSQL authentication method.

[Carlos Ruiz]

The key is the message "authentication method 10 not supported". It seems that PostgreSQL client library's version is older and does not support that encryption method. Versions 10 and later supports it.

 I wonder if that's more a function of the PostgreSQL client library version/capabilities. Do you know what MapServer is compiled against? You might try connecting to your database with psql as another test of the client lib.

I recently tried a Mapserver layer connected to a PostgreSQL 13.2 database that had password_encryption = scram-sha-256.  I was unsuccessful in getting it to work until I switched it to md5 and reset the passwords.  The following error was logged and the interesting part seems to be (authentication method 10 not supported).

Is this an issue with MapServer?  If so, will scram-sha-256 authentication be supported by Mapserver?

Thanks,
