We would like to have different reviewboard sites for different projects, each one administered by a one member of the project. We need to authenticate all users through LDAP, but let the site administrator decide who will be able to access his reviewboard site. Current implementation (1.5.2) automatically creates the user from the ldap information after the user is successfully authenticated. It would be nice to make this user creation optional. Here is the thread in google groups with this subject: https://groups.google.com/d/topic/reviewboard/AgzdVmgMdFo/discussion
Also wondering if there is an update on this. It would be very helpfull to disable the ldap auto account creation.
