|
|||
* Handle email alias defined in LDAP, and translate them into aliases in Zimbra
|
||||
* Allow objects (aliase, distribution list) to be created directly in Zimbra. Objects coming from LDAP are synchronized, including alias previously defined in LDAP which aren't anymore are removed from Zimbra. But aliases defined directly in Zimbra won't be touched. Same is true for distribution lists. So you can mix LDAP defined and Zimbra defined configuration
|

|

A few other features are included, like :
|

* Creating domains
|

* Creating / removing domain aliases

All from a simple yaml configuration file

## Configuration

The configuration is stored in a single file in YAML format. The script will look for a config at /opt/zimbra/conf/zmldapsync.yml or trhe one specified in the --config argument.
