When a user is created automatically via Service Desk LDAP Integration with Active Directory or any LDAP server, the users notification methods are set to None.
By default the notification method is set to "None".
1) Create a mod file with contents below:
MODIFY cnt notify_method1 ON_NEW DEFAULT 1800;
MODIFY cnt notify_method2 ON_NEW DEFAULT 1800;
MODIFY cnt notify_method3 ON_NEW DEFAULT 1800;
MODIFY cnt notify_method4 ON_NEW DEFAULT 1800;
//Place some white space at the bottom of the file.
2) Save the file as "zcontact.mod" under $NX_ROOT\site\mods\majic directory, (where NX_ROOT is your service desk installation directory on primary server).
3) Recycle Service Desk services after this change.
As with any customization, please be sure to test this change in a lab environment prior to placing it in production.
