Emil Anca created AMBARI-10513:
----------------------------------
Summary: ambari-server sync-ldap fails if there are too many users
in the LDAP server (more than 1000?)
Key: AMBARI-10513
URL: https://issues.apache.org/jira/browse/AMBARI-10513
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Emil Anca
Fix For: 2.1.0
ambari-server setup-ldap was performed against QE AD server, which has more
than 2000 users.
[root@c6401 ~]# ambari-server sync-ldap --all
Using python /usr/bin/python2.6
Syncing with LDAP...
Enter Ambari Admin login: admin
Enter Ambari Admin password:
Syncing all.......ERROR: Exiting with exit code 1.
REASON: Caught exception running LDAP sync. [LDAP: error code 4 - Sizelimit
Exceeded]; nested exception is javax.naming.SizeLimitExceededException: [LDAP:
error code 4 - Sizelimit Exceeded]; remaining name
'CN=Users,DC=scl42,DC=hortonworks,DC=com'
Dilli Arumugam told me that Ranger (formerly known as XASecure) also hit a
similar issue: BUG-23578.
BUG-31217: Attempting to sync LDAP that contains > 1000 entities fails.
Problem: If your directory contains > 1000 users, attempts to sync-ldap users
and groups to Ambari will fail. There is a limit of 1000 to the number of
entities Ambari can process.
Solution: Perform the sync-ldap using the --users and --groups option to limit
the amount of entities to be under 1000 and perform the sync in batches.
