Is there a way to link an SQL database to an LDAP server

We have an SQL contacts database that links into all our project information with lots and bells and whistles.

It has recently been suggested that we make the contacts part of this information available to our end users in their email clients - so we are looking at setting up an LDAP 开发者_开发技巧server

Are there any out there that will allow us to map the information in the DB (probably a view I'd suspect) to an LDAP server?
