Specifies the DN of the node where the search for the user's MSISDN number should start. There is no default value. The field will recognize any valid DN. Multiple entries must be prefixed by the local server name. The format is servername|search dn.
For multiple entries:
servername1|search dn servername2|search dn servername3|search dn...
If multiple entries exist under the root organization with the same user ID, then this parameter should be set so that the only one entry can be searched for or found in order to be authenticated. For example, in the case where the agent ID and user ID is same under root org, this parameter should be ou=Agents for the root organization to authenticate using Agent ID and ou=People, for the root organization to authenticate using User ID.
