I was trying out GitLab EE and ran into some install issues on RHEL5 (which were solvable - http://www.digitalsanctuary.com/tech-blog/general/installing... ). However even after a couple days I was unable to get the LDAP integration and LDAP group permissions to work correctly. GitLab support wasn't able to solve it for me, so I tried Stash. 30 minutes later, up and running the way I wanted it.
