Error while Selecting LDAP Authentication in Talend Data Catalog

I am implementing LDAP External Authentication in Talend Data Catalog (on-premise installation).

Currently, I am logged in with a native user account that has administrator rights.

The first step I took was to explore the supported LDAP authentication methods.

I navigated to Users > Change Authentication and switched from Native to LDAP.

However, I immediately encountered an error popup:
Cannot invoke "MITI.server.services.authentication.ldap.LdapAttributes.getLogin()" because the return value of "MITI.server.services.authentication.ldap.LdapServer.getAttributes()" is null.

After clicking OK, I was prompted to input LDAP credentials.

The interface required me to select an LDAP type from a dropdown menu, but no options were available. This contradicted the documentation, which lists several options, including:

Microsoft Active Directory
Open LDAP
IBM Tivoli
Novell eDirectory
Sun System Directory
Custom

I need assistance resolving these issues and configuring LDAP successfully in Talend Data Catalog.
