Hello @rohitcts ,
All these methods are available in LDAP authentication.
Here are the definitions.
Encrypted password ( md5 )
Default mode.
Plain text password + SSL ( TLS )
The entire authentication procedure (password included) is encrypted. The secure port 636 must not be used in this mode: Adobe Campaign automatically switches to secure mode.
When you use this authentication mode, in Linux, the certificate is verified by an openLDAP client library. We recommend using a valid SSL certificate so that the authentication procedure is encrypted. Otherwise, information will be in plain text.
The certificate is also verified in Windows.
Windows NT LAN Manager ( NTLM )
Proprietary Windows authentication. The Unique identifier is used for the domain name only.
Distributed Password Authentication ( DPA )
Proprietary Windows authentication. The Unique identifier is used for the domain name only (domain.com).
Plain text password
No encryption (for use in test phases only).

For OpenLDAP, I beileve only Plain text is available.
