OpsManager mongodb deployment issue adding PLAIN auth - mongodb

Question

I'm trying to enable PLAIN authentication security over a mongodb replica shard managed with OpsManager following their documentation https://docs.opsmanager.mongodb.com/v4.0/tutorial/enable-ldap-authentication-for-group/ .
The issue I'm facing is at the automation-agent trying to get mongoS status while restarting after enabling security. Please see the error output below:
<mongos_5> [09:18:19.711] Failed to compute states :
<mongos_5> [09:18:19.711] Error calling ComputeState : <mongos_5> [09:18:19.632] Error getting current config from running mongo using conn params = mongos01:27017 (local=false) :

identityUsed= : command serverStatus requires authentication
I noticed that even if opsmanager is not able to get the status the security was enabled successfully and PLAIN authentication mechanism works but the status hangs at
Start the process ... Start MongoDB process
I tried this over the API following mongodb-labs repo https://github.com/mongodb-labs/mms-api-examples/blob/master/automation/api_usage_example/configs/security_ldap_cluster.json but also manually following mongodb docs but everytime I'm facing the same error.

Answer 1

After all I enabled LDAP(PLAIN) only for mongo in mongoconfig file (see below the ops manager API snippet call example), and avoid enable in opsmanager for the agents also.
