After running rehost utility we are getting error that source has replication- LDAP error code 53

[PD_10631511]

After running rehost utility we got error : LDAP error code 53. 

we checked the following article : https://www.ptc.com/en/support/article/CS328255 and come to know this is happening because source has replication.

Now our target does not have replication , so the error is understood. 

So we are proceeding to disable the replication following the steps in  : 

https://www.ptc.com/en/support/article/CS376575

We get error : LDAP error code 49 - invalid credentials. 

In this disable replication command , we are giving LDAP user name and password same as in the rehost.properties file as shown : 

Can you tell me where we are going wrong ? Do we need to provide any other username password here. ? 

If yes , then which file will contain it ?

As i know LDAP error code 53 suggests that the rehost utility encountered an issue while attempting to replicate data from the source LDAP server. To resolve this error, you should investigate the underlying problem that is preventing the replication process from functioning correctly.
