Google secure LDAP client for user authentication
Please implement Google secure LDAP client (with cert).
We have to install a LDAP proxy like sTunnel to connect to Google secure LDAP for user authentication in UTM. This could be avoided.
Your post leaves a lot of things unclear. UTM already supports LDAP as a remote authentication service, including support for LDAP with Encryption over port 636. What you want to do may already be implemented.
