Title:
the speed of query user from ldap server is very slow
Status in Ubuntu Cloud Archive:
New
Status in OpenStack Identity (keystone):
Fix Released
Status in keystone package in Ubuntu:

Bug description:
In our project, the speed of query user from ldap server is very
slow,our ldap user number is 12,000,the query costs almost 45 seconds
The reason is that keystone will generate the uuid for the ldap users one by
one and insert db.And second query time later,it also goes to db,not use the
cache.
So adding the cache to improve the query speed
After adding @MEMOIZE to the following function
https://github.com/openstack/keystone/blob/master/keystone/identity/core.py#L580.
First query time almost costs 50 seconds,but second query time later it only
costs 7 seconds.
So it is very necessary to improve this feature
