Hi @avinash.m,

This error relates to configuring the AD/LDAP Connector. Specifically, it seems the error comes from trying to decrypt an empty password. I would need to see your config.json file to investigate the issue further.

Here are two resources that could help:

- [Troubleshoot AD/LDAP Connector](https://auth0.com/docs/troubleshoot/integration-extensibility-issues/troubleshoot-ad-ldap-connector)

- [Configure AD/LDAP Connector Authentication with Kerberos](https://auth0.com/docs/authenticate/identity-providers/enterprise-identity-providers/active-directory-ldap/ad-ldap-connector/configure-ad-ldap-connector-with-kerberos)
