This performs an LDAP query against the remote server searching for users and groups in a container. In order to migrate passwords you need to bind as a user that can read the userPassword attribute on the remote server. This is generally restricted to high-level admins such as cn=Directory Manager in 389-ds (this is the default bind user). The default user container is ou=People. The default group container is ou=Groups. Users and groups that already exist on the IPA server are skipped. Two LDAP schemas define how group members are stored: RFC2307 and RFC2307bis. RFC2307bis uses member and uniquemember to specify group members, RFC2307 uses memberUid. The default schema is RFC2307bis. The schema compat feature allows IPA to reformat data for systems that do not support RFC2307bis. It is recommended that this feature is disabled during migration to reduce system overhead. It can be re-enabled after migration. To migrate with it enabled use the "--with-compat" option. Migrated users do not have Kerberos credentials, they have only their LDAP password. To complete the migration process, users need to go to http://ipa.example.com/ipa/migration and authenticate using their LDAP password in order to generate their Kerberos credentials. Migration is disabled by default. Use the command ipa config-mod to enable it: ipa config-mod --enable-migration=TRUE If a base DN is not provided with --basedn then IPA will use either the value of defaultNamingContext if it is set or the first value in namingContexts set in the root of the remote LDAP server. EXAMPLES: The simplest migration, accepting all defaults: ipa migrate-ds ldap://ds.example.com:389 Specify the user and group container. This can be used to migrate user and group data from an IPA v1 server: ipa migrate-ds --user-container='cn=users,cn=accounts' \\ --group-container='cn=groups,cn=accounts' \\ ldap://ds.example.com:389 Since IPA v2 server already contain predefined groups that may collide with groups in migrated (IPA v1) server (for example admins, ipausers), users having colliding group as their primary group may happen to belong to an unknown group on new IPA v2 server. Use --group-overwrite-gid option to overwrite GID of already existing groups to prevent this issue: ipa migrate-ds --group-overwrite-gid \\ --user-container='cn=users,cn=accounts' \\ --group-container='cn=groups,cn=accounts' \\ ldap://ds.example.com:389 Migrated users or groups may have object class and accompanied attributes unknown to the IPA v2 server. These object classes and attributes may be left out of the migration process: ipa migrate-ds --user-container='cn=users,cn=accounts' \\ --group-container='cn=groups,cn=accounts' \\ --user-ignore-objectclass=radiusprofile \\ --user-ignore-attribute=radiusgroupname \\ ldap://ds.example.com:389 """) # USER MIGRATION CALLBACKS AND VARS _krb_err_msg = _('Kerberos principal %s already exists.
