Public bug reported:

Recently applied security update to 14.04.5 LTS kerberos (1.12+dfsg-
2ubuntu5.4), and started getting errors when adding new principals to
LDAP.

Obfuscated example:

kadmin.local -q "ank -x dn=\"uid=testuser,ou=People,dc=example,dc=com\"
-pw \"dummypass\" testuser"

now gives:
Authenticating as principal root/admin@xxxxxxxxxxxxxxxx with password.
NOTICE: no policy specified for testuser@xxxxxxxxxxxxxxxx; assigning "default"
add_principal: DN is out of the realm subtree while creating "testuser@xxxxxxxxxxxxxxxx".


This worked up through 1.12+dfsg-2ubuntu5.3, and I think it now fails due to changes in src/plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in response to CVE-2018-5729 or CVE-2018-5730.

I'm going to attempt a downgrade to 1.12+dfsg-2ubuntu5.3 to check.
