| Doc Text: |
Cause: An LDAP object migrated via migrate-ds command may contain multi-valued RDN attribute. However, migrate-ds process just picks the first value of the RDN attribute and does not respect the value that was present in the DN in the migrated LDAP object
Consequence: Migrated LDAP object may contain invalid RDN. If there is another LDAP object with the same RDN value, migrate-ds process reports error and fails to migrate these objects
Fix: Do not pick the first value of multi-valued RDN but use the value that is used in original LDAP object DN
Result: LDAP objects with multi-valued RDN attribute are migrated without error

ldif of the group that I am expecting to migrate
Additional: the other groups in this ou do seem to migrate properly. I have some machines to play with if you need a working setup. What groups migrated? Do you have the output of the migration command (or can you duplicate it)? It should list the groups that aren't migrated and a reason. The groups that are migrated are: accounting managers, hr managers, pd managers, qa managers The output from the migrate command is as follows: ----------- migrate-ds: ----------- Migrated: user: user2000, user1000, user2009 group: accounting managers, hr managers, qa managers, pd managers Failed user: Failed group: ---------- Passwords have been migrated in pre-hashed format. IPA is unable to generate Kerberos keys unless provided with clear text passwords. All migrated users need to login at https://your.domain/ipa/migration/ before they can use their Kerberos accounts. Upstream ticket: https://fedorahosted.org/freeipa/ticket/1892 The problem here is that migrated groups contained multivalued CN used in group's RDN. Migrate process just took the first RDN attribute value and since it was already migrated ("pd managers") it didn't add it.
My plan is to take the attribute value used in the DN and not just the first one.
Fixed upstream: master: https://fedorahosted.org/freeipa/changeset/56d89d39cef552336deaa8852ae62fd88c270a9b ipa-2-1: https://fedorahosted.org/freeipa/changeset/46c16ed6ec14af3b4ee5b76c4353d9cc12d35a11

Verified against ipa-server-2.1.3-8.el6.x86_64 Used the same test that I used when I created this bug report. Output of the test containing the groups that I am expecting. :: [ PASS ] :: enabling migration ----------- migrate-ds: ----------- Migrated: group: group1000, group2000 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Created attachment 525238 [details] This is a dump of the entire group ou to migrate Description of problem: Starting with a configured DS server containing a group ou of ou=Groups,dc=bos,dc=redhat,dc=com, When you add a new group to that ou, I expect that the group will get migrated along with the other groups in that ou. migrate-ds seems to only migrate some of the groups. Version-Release number of selected component (if applicable): ipa-server-2.0.0-23.el6.x86_64 How reproducible: always Steps to Reproduce: 1. create ds setup containing the group ou of ou=Groups,dc=bos,dc=redhat,dc=com 2. add the user specified in the attached user-to-add.ldif 3. run "ipa migrate-ds" to migrate from that server. 4. search for that user in the new IPA Actual results: [root@ipaqa64vmb ds-migration]# ipa group-find group1000 ---------------- 0 groups matched ---------------- ---------------------------- Number of entries returned 0 ---------------------------- Expected results: Additional info: Error logs look good during the migration, my speculation is that the ldap query isn't picking up all of the groups to migrate.
