Allow HTTPd user to access SSSD IFP
For smart card and certificate authentication, Apache's
mod_lookup_identity module must be able to acess SSSD IFP. The module
accesses IFP as Apache user, not as ipaapi user.
Apache is not allowed to use IFP by default. The update code uses the
service's ok-to-auth-as-delegate flag to detect smart card / cert auth.
