Identity Management attempts to retrieve the LDAP schema from the remote server during migration. Previously, such an attempt failed when migrating from an OpenLDAP server. With this update, Identity Management also looks in cn=subschema and migrations from OpenLDAP servers no longer fail.

Fixed upstream: master: 959b276e7d10f80269568c6d340e59d664fc5d42 ipa-3-1: 2b491acb4ad4d6880cabff02b474d6885af8242b ipa-3-0: dd499c559c960f8c01287bcfe28c158e3780daa4 Please add steps to reproduce / verify this issue. How to make schema unavailable? This bug also needs to be cloned for inclusion in RHEL 7.0 (In reply to comment #5) > Please add steps to reproduce / verify this issue. How to make schema > unavailable? This bug also needs to be cloned for inclusion in RHEL 7.0 We used to read LDAP schema only from "cn=schema" DN, its presence can be verified with for example this ldapsearch: # ldapsearch -h $HOST -D "cn=Directory Manager" -W -x -b cn=schema objectClasses attributeTypes This applies both for local LDAP operations like standard ipa commands and also for migration which can read from remote LDAP which may not be 389-ds. This lead to a missing schema error when running "ipa migrate-ds" command for openldap LDAP server which has a schema in different DN: "cn=subschema". To reproduce: 1. On one VM, configure an openldap server with some users and groups 2. On other VM, configure IPA server: ipa-server-install 3. Enable migration mode: ipa config-mod --enable-migration=TRUE 4. Run migration: ipa migrate-ds ldap://$HOST_WITH_OPENLDAP_SERVER ... Without this fix, this command always crashes with schema error. Cloning for RHEL 7.0... Verified using ipa-server-3.0.0-33.el6.x86_64.
