Datastax OpsCenter LDAP Configuration Error

[dvsrk]

I have configured LDAP settings for Datastax opsCenter authentication. Though the application is able to find the account in the search (got this details by enabling debug option for additional logging), but at the end getting an exception as below,

2017-05-05 22:30:18,658 [opscenterd] DEBUG: Unbind successful (PoolThread-twisted.internet.reactor-2)
2017-05-05 22:30:18,658 [ClusterTest] DEBUG: received a NoD, closing everything (NioProcessor-1)
2017-05-05 22:30:18,662 [opscenterd]  WARN: Unauthorized while calling LoginController: User filter insufficient to uniquely identify users. (MainThread)

Below are the LDAP settings i have configured in my configuration file (opcenterd.conf),

server_host = myad01.test.domain.com    
server_port = 389    
uri_scheme = ldaps     
search_dn = CN=ldap-account,OU=Service Accounts,DC=test,DC=domain,DC=com     
search_password = *******    
user_search_base = dc=test,dc=domain,dc=com     
user_search_filter = (sAMAccountName={0})     
admin_group_name = DB Admin, DB Dev    
user_memberof_attribute = memberof

Could someone guide me if i'm missing anything here? Also, please route me to the right group if this is not the right one to post this question.
