You can remove members from an integrity QOP. Just substitute the remove: attribute for the add: attribute shown in Assigning Members to an Integrity QOP Policy, and remove the unneeded members. For example:
dn: cn=high,cn=integ-qops,cn=policy1,cn=tdatrootP,dc=domain1,dc=com changetype: modify remove: member member: cn=jcm,cn=users,cn=systemone,cn=tdatrootA,dc=domain1,dc=com -
