Create indexes for altSecurityIdentities and ipaCertmapData attributes
During an investigation into filter optimisation in 389DS it was
discovered that two attributes of the certmap query are unindexed.
Due to the nature of LDAP filters, if any member of an OR query is
unindexed, the entire OR becomes unindexed.
This is then basically a full-table scan, which applies the filter test
to the contained members.
