This bug is created as a clone of upstream ticket: https://fedorahosted.org/freeipa/ticket/3372 When trying to migrate data from ldap using the following command. ipa migrate-ds --bind-dn="cn=admin,dc=example,dc=com" --user-container="ou=ib,dc=example,dc=com" --group-container="ou=groups,ou=live,dc=example,dc=com" ldaps://ldap1.example.com:636 I get the following error {{{ ipa: DEBUG: stderr= ipa: DEBUG: Caught fault 4203 from server http://fedoraipaserver.test.example.com/ipa/xml: uri=ldaps://ldap1.example.com:636: Unable to retrieve LDAP schema: No such object: ipa: DEBUG: Destroyed connection context.xmlclient ipa: ERROR: uri=ldaps://ldap1.example.com:636: Unable to retrieve LDAP schema: No such object: }}} This apparently is due to a check of the ldap schema before migrating the data. Not sure how this should be fixed Regards John
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...
