<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">A suggestion has been made to add additional lookup constraints via a filter. The problem with read only LDAP databases is that you are not able to tag the
keystone users with any flags to indicate that they are keystone users. The current Keystone H-2 LDAP backend code performs the _ldap_get_all function (which took 1 ½ hours today) and must then look to see which of those users are in the keystone database
because the REST API call only returned the one user that I had assigned a project role to. I am thinking that this logic is backwards. Instead of starting with the LDAP server, start by querying the keystone SQL database for LDAP users and then query the
LDAP system for those users a certain number at a time (good use of pagination). By the way, I am assuming that keystone finds the LDAP users by looking in the user_project_metadata, user_group_membership_ anduser_domain_metadata tables for user IDs that are
not in the user table.</span><o:p></o:p></p>
</blockquote>
<p class="MsoNormal"><br>
We should probably just drop the list_user functionality from Keystone, as it probably doens't belong there. listing users in a project it probably fine, but all users in the system only makes sense for really trivial systems.<br>
<br>
Most LDAP servers limit the number of records returned. I know in FreeIPA, we had 200 records, and then you needed a filter to find what you wanted beyond that. Pagination is a bettersolution, although I shudder to think of the impact of all those live cursors
on a heavily loaded Enterprise directory.<br>
