In combination with this MobileIron document:
If you are getting Error Code 32 which means that the LDAP config isn’t configured correctly and you have checked and double checked the config, it could just be a case of “case sensitity”. In theory it shouldn’t matter but it does. Check that the Base DN for your search has the domain name as per ADSIEDIT.
i.e. awesomecompany.LOCAL should be DC=awesomecompany,DC=LOCAL.
Hope this helps…
