Overview

Currently the provisioning code for different backends are clumped together in a single Python class. It uses a number of if-then statements to control the path of the code. To improve manageability the code should be refactored into several classes utilizing more object-oriented techniques.

Class Hierarchy

ProvisionBackend
+ LDBBackend
+ ExistingBackend
+ LDAPBackend
  + FDSBackend
  + OpenLDAPBackend

ProvisionBackend

The ProvisionBackend is the base class for all Samba backend classes. It defines some methods that should be overridden by the subclasses:

• init() - initializing backend
• start() - starting backend
• shutdown() - shutting down backend
• post_setup() - post-setup configuration

LDBBackend

The LDBBackend is the default TDB backend.

ExistingBackend

The ExistingBackend is used with an existing LDAP server.

LDAPBackend

The LDAPBackend is used with a new LDAP server. It defines a method that should be overridden by the subclasses:

• provision() - backend specific provisioning steps

FDSBackend

The FDSBackend is used with 389 DS server.

OpenLDAPBackend

The OpenLDAPBackend is used with OpenLDAP server.
