*1 When obtaining user groups, check the following:

The user account that can obtain user groups is sAMAccountName (user). Do not use UserPrincipalName (user@domain.xxx.co.jp) as the user name.
Check whether the name in "Group" is correctly specified including the case-sensitivity in [Settings][Machine Features Settings][System Settings][Administrator Tools][User Authentication Management][Windows Authentication].
Select the user in the address book, press [Edit], and then check that [User Management / Others] tab [User Management][Available Functions / Applications] is not selected.
Check whether "Global Scope" is specified as the scope of the group in a property for the user group created in DC, and the group type specified in "Security". Also check whether an account is registered to the user group that has been created. If more than one DC exists, check whether a trust relationship between DCs is established.

*2 To resolve the domain name, see the following:

Check whether [Domain Name] and [DNS Configuration] is specified correctly in [Settings][Machine Features Settings][System Settings][Interface Settings][Network].
Enter the IP address in [Domain Name] to check the connection. If authentication can be performed using the IP address, check [DNS Configuration] again.
If authentication by IP address is not possible, check whether LM/NTLM is set to be denied in the domain controller security policy or domain security policy. Also check that the port is not closed in the firewall between the device and the domain controller or in the firewall settings of the domain controller. When the Windows firewall is enabled, create a new rule that allows communication on port 137 and port 139 in "Advanced" of the Windows firewall. Open the TCP/IP properties from the network connection properties, select the "Enable NetBIOS Over TCP/IP" check box on the [Advanced] [WINS] tab, and open port 137.

*3 For Kerberos authentication, check the following:

Check that "Realm Name", "KDC Server Name", "Domain Name" are specified correctly in [Settings][Machine Features Settings][System Settings][Administrator Tools][Program/Change/Delete Realm]. Enter "Realm Name" in upper case.
Configure the setting so that the difference in time between the clocks on KDC and device is less than five minutes. The clock on the machine can be adjusted in [Settings][Machine Features Settings][System Settings][Timer Settings][Set Time].
Kerberos authentication fails if auto-obtaining of KDC in Windows authentication fails. When auto-obtaining cannot be activated, switch to manual.

*4 For LDAP settings, check the following:

Check whether the LDAP server is correctly specified in [Settings][Machine Features Settings][System Settings][Administrator Tools][User Authentication Management][LDAP Authentication] and Login Name Attribute is registered correctly.
Check that the representative account is registered in "Authentication" "Kerberos Authentication" under [Settings][Machine Features Settings][System Settings][Administrator Tools][Program/Change/Delete LDAP Server], and then execute [Connection Test].
Programming the LDAP Server
If the connection test fails, check whether [Domain Name] and [DNS Configuration] is specified correctly on the [Settings][Machine Features Settings][System Settings][Interface Settings][Network].
