#6549 replica install against IPA v3 master fails with ACIError

Closed: fixed 7 years ago Opened 7 years ago by mbabinsk.

When attempting to install a replica against an old (3.0.0) master, the installation fails when requesting keytab for DS:

[26/44]: enabling SASL mapping fallback
  [27/44]: restarting directory server
  [28/44]: creating DS keytab
  [error] ACIError: Insufficient access: Insufficient 'add' privilege to add the entry 'krbprincipalname=ldap/replica2.ipa.test@IPA.TEST,cn=services,cn=accounts,dc=ipa,dc=test'.
Your system may be partly configured.
Run /usr/sbin/ipa-server-install --uninstall to clean up.

The root cause of this issue is probably caused by the fact that the remote connection in domain level 0 is created using host keytab of using Directory Manager password. Since ACIs permitting hosts to manage their own services were added in 4.2 release the old master denies this operations.

For this reason domain level 0 replica install should always use Directory manager credentials to create remote LDAP connection.
