Hi pgsql-admin mailing list, I'm having some problems setting up access privileges via pg_hba.conf. The problem is that it seems that some Linux user accounts have password-less access to the pgsql databases via the 'pgsql' CLI tool even though I try to enforce md5 password protection. The relevant line in pg_hba.conf is this: host all mette,mkrist 10.10.0.0 255.255.0.0 md5 If I'm logged in as the Linux user "mkrist" and try to log in to a database as either the pgsql user "mette" or the pgsql user "mkrist" it requires me to enter a password (which it then accepts and logs me in). But if I'm OTOH logged in as the Linux user "mette" it only requires me to enter a password if I try to login to a database with the pgsql user "mkrist" (which it then accepts). If I try to login as the pgsql user "mette" it logs in without asking for a password. I can't find anything in the documentation about exceptions from the pg_hba.conf rules, so I'm quite surprised by this behaviour. Thank you, I'd appreciate any help. -- Michael Kristensen <mkrist@xxxxxxxxxx> IT-studentermedhjælper / Sysadm student aid BINF
