Issue

A failed ipa group-add-member operation reports the problem like this:

  Failed members: 
    member user: user2: Insufficient access: Insufficient 'write' privilege to the 'member' attribute of entry 'cn=testgroup,cn=groups,cn=accounts,dc=ipa,dc=example'.
    member group: 
    member service: 

However ipa group-add-member-manager does not report the error although the error message is in the returned JSON.

Steps to Reproduce

1. kinit unprivilegeduser
2. ipa -vv group-add-member testgroup --users user2
   3.

Actual behavior

The command does not report failed members.

Expected behavior

The command should report failed members.
