gitlab-rake gitlab:check SANITIZE=true does not sanitize LDAP users

Summary

When I launch gitlab-rake gitlab:check SANITIZE=true does not sanitize LDAP users I expect data to be obfuscated to pass them to issue trackers or similar.

However, when I launch with SANITIZE=true it outputs my LDAP users.

Steps to reproduce

Launch gitlab-rake gitlab:check SANITIZE=true does not sanitize LDAP users when you have LDAP installation.

Expected behavior

Don't see the users name or obfuscate them (Albert Einster, Hillary Trump, Mickey Trump, Donald Mouse etc)

Actual behavior

It shows reals data.

Relevant logs and/or screenshots

First listed users (it lists up to 100):

LDAP users with access to your GitLab server (only showing the first 100 results)
Server: ldapmain
        DN: cn=Rafal Zawadzki,ou=users,dc=idoru,dc=pl    uid: bluszcz

Output of checks

All checks are OK.
