If you are looking at this post, you would have already installed reviewboard and are facing issues configuring LDAP on it. For others who landed here by chance: Review Board is a powerful web-based code review tool that offers developers an easy way to handle code reviews. It scales well from small projects to large companies and offers a variety of tools to take much of the stress and time out of the code review process. You can checkout reviewboard @ http://www.reviewboard.org/ Now comming to the topic, reviewboard asks for the following LDAP settings: LDAP Server : ldap://<your server ip>:389 (By convention this can be : ldap://ldap.<your company name>.<com|net|org>:389) LDAP Base DN (Used to perform LDAP searches) : Should generally be composed of OU & DC. For ex:- OU=users,OU=<US|Canada|AsiaPac|Japan>,OU=<(Engineering|Eng)|(Finance|Fin)),DC=<yourcompanydomain>,DC=<com|net|org> example1: OU=users,OU=AsiaPac,OU=Eng,DC=GooG,DC=com
