Reset SysAdmin password not working for OPDK 4.19.01

[priniren]

I tried resetting the system admin email and password using the instructions provided in https://docs.apigee.com/private-cloud/v4.19.01/resetting-passwords#resetsystemadminpassword. However, It doesnt appear that the password change has taken effect. I am not able to recover the old password as well.

What is the way out? Is it possible to reinstall OpenLDAP and create users all over again? This is for a 5 node Apigee OPDK installation.
