I work in a startup company and recently the number of pieces of software we use started to increase. Because all of them introduce their own user databases I started looking for a solution that could be integrated with them and save me the time of updating every single db when someone compromises a password/joins/leaves.
So far I see that the only solution that is used more widely is ldap. I had bad experience with it in the past, so I was wondering if anyone could recommend an alternative.
For now it would be sufficient if it could be integrated with svn, apache and had php bindings. It would be even more awesome if it could integrate with git, ftp, postfix.
