StartTLS is NOT the same as LDAPS. Please, clarify.
In addition, make sure you have the certificates required to perform the validation, or disable the certificate validation in the user_ldap wizard.

Hi jvillafanez,

Sorry, new to this forums.

We are trying to setup ldap to MacOS which uses TLS. and the options don’t work.

I will try the settings with disabling certificate validation now and update.

Thanks
