The compatibility mode can be read using dsconf command as follows:
$ dsconf get-server-prop pwd-compat-mode
The pwd-compat-mode property can have one of the following values:
The purpose of DS5-compatible-mode is to allow an existing replicated topology to be migrated from Directory Server 5.2 instances to Directory Server 11g Release 1 (11.1.1) instances. A Directory Server 11g Release 1 (11.1.1) instance in DS5-compatible-mode accepts updates containing either old or new password policy attributes, and produces updates containing both sets of attributes. Updates can arrive from an LDAP client or from replication, and changes are produced locally as a result of password policy evaluation (for example, as a result of a failed authentication or a password change). Note that any version 5.2 instance consuming replicated updates produced by a version 11g Release 1 (11.1.1) instance (either directly or through another instance) must have its schema updated with 00ds6pwp.ldif as described in Issues With the Password Policy in Oracle Fusion Middleware Upgrade and Migration Guide for Oracle Directory Server Enterprise Edition. While the Directory Server 5.2 instance will ignore any new attributes during password policy processing, when an entry containing the new attributes is modified at that instance, without the schema update, the schema check will fail when the modified entry is written.
DS6-migration-mode is an intermediate step between DS5-compatible-mode and DS6-mode, All policy decisions are based on the new password policy attributes and the old (Directory Server 5.2) password policy attributes are removed from the server's data. Since the number of policy configuration entries is small, the old password policy configuration attributes are cleaned from all policy entries as soon as the instance is advanced to DS6-migration-mode. However, the cleanup of a user entry is deferred until the entry is modified as part of normal password policy processing during a password modify operation. This approach allows the cleanup to proceed gradually, so as to not degrade the server's performance. The modifications necessary to remove any old policy attributes are not replicated so that they do not interfere with the operation of instances still in DS5-compatible-mode.
A Directory Server instance in DS6-mode uses only new policy attributes in computing password policy decisions. Any old password policy attributes remaining in an entry are ignored.
The compatibility mode is set using the dsconf command as follows:
$ dsconf pwd-compat new-mode
The new-mode action takes one of the following values:
Change to DS6-migration-mode from DS5-compatible-mode.
Once the change is made, only DS6-migration-mode and DS6-mode are available.
Change to DS6-mode from DS6-migration-mode.
Once the change is made, only DS6-mode is available.
The server state can move only towards stricter compliance with the new password policy specifications.
The DS5–compatibility-mode password policy is deprecated. You must switch to DS6–mode password policy in this version.
