# Test some simple LDAP requests using the ldap2 backend

# This fetches a certificate from a host principal so we can ensure that the
# schema is working properly. We know this because the schema will tell the
# encoder not to utf-8 encode binary attributes.

# The DM password needs to be set in ~/.ipa/.dmpw
