Thank you for the response! No, no... these are example data that I put together to understand how Google users are structured and the issue that uppercase letters are causing me. In the Google LDAP audit, I see that the user fails and appears in lowercase.

Once again, I apologize; I ran so many tests that I accidentally copied one where the binddn was incorrect.

The target looks more like this:

## example.com uri "ldaps://ldap.google.com/dc=proxy" suffixmassage "dc=proxy" "dc=example,dc=com" lastmod off readonly on idassert-bind bindmethod=simple binddn="cn=ChiwewDaw" credentials="password-fake" tls_reqcert=demand tls_reqsan=demand starttls=critical tls_cert=/root/ldapcerts/ldap_cert.crt tls_key=/root/ldapcerts/ldap_cert.key tls_cacert=/root/ldapcerts/ca/gtsr1.pem

if i use:

idassert-bind bindmethod=sasl saslmech=EXTERNAL tls_reqcert=demand tls_reqsan=demand starttls=critical

i have the error : "Unauthenticated"
