Google LDAP Auth for Global Protect

[joebauman]

Has anyone been able to use the Google LDAP service for authentication for GlobalProtect users?  I haven't been able to get the firewall to successfully connect to the Google LDAP service.  Google suggests cert based authentication to the service and provides a cert but the firewall rejects the import with the following error 

"Import of google-ldap failed. Only self signed CA certificates can have identical subject and issuer fields."

I have also attempted a test via the cli and get the following.

admin@fw01> test authentication authentication-profile gsuite-ldap username xyz password
Enter password : 

Target vsys is not specified, user "xyz" is assumed to be configured with a shared auth profile.

Do allow list check before sending out authentication request...
name "xyz" is in group "all"

Authentication to LDAP server at ldap.google.com for user "xyz"
Egress: 10.12.29.8
Type of authentication: GSSAPI
Starting LDAPS connection...
Failed to create a session with LDAP server
Authentication failed against LDAP server at ldap.google.com:636 for user "xyz"


Authentication failed for user "xyz"

Any help would be much appreciated!

I'm having the same issue, not able to import google's certificates (as they are self-signed by google) and not getting any connectivity at all (like what Joebauman is showing as well). Google's LDAP Client uses certificate authentication as the primary authentication mechanism, from what I'm seeing it doesn't look like Palo Alto supports this but I'd love to be proven wrong.

I confirmed with both Google and Palo Alto that there is no work around for this issue.  I went with Foxpass for LDAP and it works great!  It will sync with your gsuite user/groups.

Thanks for the tip. I was having the same issue and this product looks like it will solve the problem and not too pricey.

I am sorry this is not an acceptable answer PA needs to figure out how to make this work.
