Has anyone ever got this to work using Postgres?

Yeah Ive had it working fine with Postgres before, are you coming up against the problem I did regards password complexity? you need to install the DB with a good password and then it works if you give it a password of 'password' it fails and gives you a poor response

Hi. Thanks for the reply. Every time I try to install Postgres I get the 'no mapping between account names and security ids was done' message. If I try to use an existing account it says it cannot find it. I have disabled the password complexity requirement. This is installing onto a domain controller. I have found that installing onto a member server works, but as far as I can see from the documentation, installing onto a domain controller should not be a problem?

Postgres user account is created as a local account (on a non-domain environment). No local user accounts can be created on a domain controller.

Install the server on a computer which is not a domain controller

Cheers,
