Active Directory 2008 cannot use Kerberos authentication. Why?

First, verify that the DNS server is configured correctly. Then check the ServicePrincipalName of Active Directory 2008 Kerberos. If the ServicePrincipalName has changed, modify the value in /opt/trend/imss/config/imss.ini.

For example:

[LDAP-Setting]

server-spn=ad2008@domain.com

$('#title').html($('meta[name=description]').attr('content'));
