Search for Users with Published Certificates in AD

Does anyone know how to find all users in AD with published certificates? My org needs to know so that we can start disabling those account that do not contain a certificate. The published certiticates cannot be seen unless you check 'advanced options' in AD users and computers. But when I want to do a search under AD i cannot use that field to search. Any clues? Thanks guys!

You can use an LDAP query tool such as dsquery (built into the 2003 operating system), LDP (in the Support Tools) or adfind (free download from www.joeware.net) to query on the userCertificate attribute. To use adfind, as an example, you would use the following syntax to return all users in your domain that have one or more certificates configured: (careful, this syntax will wrap - type it all on one line.)

adfind -default -f "(&(objectclass=user)(objectcategory=person)(userCer
tificate=*))"

To find users who -don't- have certificates, simply put a ! in front of userCertificate, like so:

adfind -default -f "(&(objectclass=user)(objectcategory=person)(!userCer
tificate=*))"

This is great. I downloaded the tool from the site you mentioned and it does what I want except I need to export this somehow in a report. The screen just keeps scrolling and scrolling with tons of info. Is there anyway to export it into a managable form (.xls, .csv, .txt)?

Thanks again!

If you want to query directly in ADUC, create a custom query entering the following under Advanced > Enter LDAP query or you can rename the attached txt file to .XML, import under Saved Queries and reset the OU:

(&(&(&(&(objectCategory=person)(objectClass=user)(!userCertificate=*)))))
