There are a number of benefits to connecting an AD/LDAP server with CACHATTO apart from having access to Exchange. AD/LDAP authentication makes using CACHATTO even easier without compromising security.
If ActiveDirectory (AD) server authentication is enabled, the shared passwords will be updated upon successfully logging into CACHATTO. AD/LDAP authentication can be used for both portals and viewing the file server.
AD/LDAP authentication also applies for access permissions on file server files both in and outside of the office.
Access permissions are maintained with AD/LDAP authentication when viewing the file server with CACHATTO.
