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/ad...@test.example.com with password.
NOTICE: no policy specified for testu...@test.example.com; assigning "default"
add_principal: DN is out of the realm subtree while creating
"testu...@test.example.com".
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.
