UPDATE: I ended up rebuilding a new Ambari server and database from scratch, and running the 'sync-ldap' command using the default credentials (admin:admin). I think changing the default credentials before syncing the LDAP users causes the sync to fail, will try to raise an issue about this in Github. Thanks @Jay SenSharma and @Vipin Rathor for your help! I used your suggestions when I rebuilt Ambari and they were very helpful! ... View more

@Vipin Rathor I cannot use the ambari-server command because that command makes a request to 127.0.0.1 (IPv4), which fails because the ambari-server is binding to ::1 (IPv6): [ec2-user@ip-192-168-12-67 ~]$ sudo ambari-server sync-ldap --all -v Using python /usr/bin/python Syncing with LDAP...

@Vipin Rathor Thank you! Binding with a manager as a user seems to have resolved the previous issue and allowed me to establish a proper connection to Windows, but now I cannot seem to form the proper curl command to sync the users. I believe the way I am feeding the username/password combination is incorrect. This is the command I'm using and the result: [ec2-user@ip-192-168-12-67 ~]$ curl -k -i -u '<user>:<password>' -H 'X-Requested-By: ambari' -X POST -d '[{"Event":{"specs":[{"principal_type":"users","sync_type":"all"},{"principal_type":"groups","sync_type":"all"}]}}]' <a href="https://localhost:8443/api/v1/ldap_sync_events">https://localhost:8443/api/v1/ldap_sync_events</a> HTTP/1.1 403 Unable to sign in.

@Jay SenSharma I changed the baseDn peoperty to match the example you gave me, still getting the same error. Has Ambari been confirmed to work with Windows Server 2012? I am concerned that it cannot interface with a newer version of Windows. ... View more

Hello @Jay SenSharma, Thanks for replying. I am using ActiveDirectory on Windows Server 2012 R2, and I confirmed it's running by using telnet from my RedHat box. I used the corrected curl command you posted, and the result is the same.

My Ambari server (RedHat 7.3) is listening on ::1 (IPv6), and when I run 'ambari-server sync-ldap', it tries to make a request to 127.0.0.1, which results in a 'Connection refused': [ec2-user@ip-192-168-12-67 ~]$ sudo ambari-server sync-ldap --all -v Using python /usr/bin/python Syncing with LDAP...
