A. Changes Since Previous Release
The following sections attempt to summarize the new features and changes in OpenLDAP software since the 2.4.x release and the OpenLDAP Admin Guide.
In order to make the Admin Guide more thorough and cover the majority of questions asked on the OpenLDAP mailing lists and scenarios discussed there, we have added the following new sections:
- When should I use LDAP?
- When should I not use LDAP?
- LDAP vs RDBMS
- Access Control
- Changes Since Previous Release
- Upgrading from 2.4.x
- Common errors encountered when using OpenLDAP Software
- Recommended OpenLDAP Software Dependency Versions
- Real World OpenLDAP Deployments and Examples
- OpenLDAP Software Contributions
- Configuration File Examples
- LDAP Result Codes
Also, the table of contents is now 3 levels deep to ease navigation.
These features were strongly deprecated in 2.4 and removed in 2.5.
back-bdb and back-hdb were signficantly slower than back-mdb and required significant tuning of multiple parameters to maximize performance. back-mdb requires no tuning and provides all the functionality previously provided via back-bdb and back-hdb.
