Migration: migrate_all_offline.sh can't handle duplicate entries
Last modified: 2013-03-03 20:27:22 EST
Description of problem: Migration script migrate_all_offline.sh can't handle duplicate entries. In case of duplicated entry in generated ldif slapadd fails, doesn't import anything. Version-Release number of selected component (if applicable): openldap-2.3.43-9.el5 How reproducible: Always. Steps to Reproduce: 1. configure OpenLDAP server (see attached slapd.conf): export LDAPHOST="127.0.0.1" export LDAP_BASEDN="dc=foo,dc=bar,dc=com" export LDAP_BINDDN="cn=Manager,dc=foo,dc=bar,dc=com" export LDAP_BINDCRED="x" export LDAP_PROFILE="no" service ldap stop mkdir /tmp/ldap-test-ldap mkdir /tmp/ldap-test-run chown ldap:ldap /tmp/ldap-test-run chown ldap:ldap /tmp/ldap-test-ldap chcon --reference=/var/run/openldap /tmp/ldap-test-run chcon --reference=/var/lib/ldap /tmp/ldap-test-ldap cp -f slapd.conf /etc/openldap/slapd.conf 2. Migrate all offline (there should be duplicated entries, see attached ldif): perl /usr/share/openldap/migration/migrate_all_offline.sh Actual results: Creating naming context entries... Migrating groups... Migrating hosts... Migrating networks... Migrating users... Migrating protocols... Migrating rpcs... Migrating services... Migrating netgroups... Importing into LDAP... Migrating netgroups (by user)... Migrating netgroups (by host)... Preparing LDAP database... bdb_db_open: Warning - No DB_CONFIG file found in directory /tmp/ldap-test-ldap/: (2) Expect poor performance for suffix dc=foo,dc=bar,dc=com. => bdb_tool_entry_put: id2entry_add failed: DB_KEYEXIST: Key/data pair already exists (-30996) => bdb_tool_entry_put: txn_aborted! DB_KEYEXIST: Key/data pair already exists (-30996) slapadd: could not add entry dn="cn=echo,ou=Services,dc=foo,dc=bar,dc=com" (line=2739): txn_aborted! DB_KEYEXIST: Key/data pair already exists (-30996) Migration failed: saving failed LDIF to /tmp/nis.ldif.x26447 Expected results: All entries all imported successfully, duplicated entries are skipped with warnings. Additional info: Script migrate_all_online.sh successfully import all even if duplicated entries are present. To achieve expected results it would be enough to add -c option to slapadd options in migrate_all_offline.sh.

Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: - use of migrate_all_offline.sh migration script while there are some duplicate accounts to be migrated - the migration process is interrupted - updated the script not to interrupt the migration process, when some error occur (e.g, when duplicate account is added) - local duplicate accounts will not interrupt the migration process
