# Authentication Problem With OS X and MacPorts
If you’re using OS X, and you’ve installed Firefox (Or in fact, anything which depends on gnome-vfs) and PostgreSQL through MacPorts, you may run into this problem :
- [11:06:14 carl@mummra ~]% sudo /opt/local/etc/LaunchDaemons/org.macports.postgresql82-server/postgresql82-server.wrapper stop
- postgres@LOCAL's Password:
That’s because when you install Firefox, Heimdal gets installed and messes up the authentication on your system, although seemingly only for the ‘postgres’ user.
To fix it, simply do
- [11:12:02 carl@mummra ~]% sudo port deactivate heimdal
