    Contacts: LDAP access to contacts on App-Platform                
                Hello,
Contacts from Contacts-App cannot be accessed via LDAP from SIP devices because the LDAP-Protocol is properitary or not fully implemented. 
If i try it, there is always an error "non-meta search unsupported!". Tested with SIP-devices and LDAP browsers
LDAP can be used for accessing the internal users of the PBX, this also should be possible for contacts on the App-Platform.
Regards
Felix
