Initializing Kerberos authentication
Follow these steps to initialize Kerberos Authentication for your product.
Embedded Kerberos Authentication uses session tickets in the authentication process.
The session tickets are time stamped by both the Kerberos Domain Controller (KDC) and the
product. It is essential that the stamped times are within five minutes of each other. This can be
accomplished by setting identical time on both the KDC and product.
Open the HP EWS in a web browser.
Select the Settings tab, and then Kerberos Authentication.
Under the Accessing the Kerberos Authentication Server section, perform the following steps:
Type the domain name in the Kerberos Default Realm (Domain) field. The domain name is
case-sensitive and must use only uppercase letters, for example: TECHNICAL.MARKETING.
Type the product IP address in the Enter the Kerberos Server Hostname field, for
example: 18.104.22.168 (IP address)
The Kerberos Server Port field fills automatically as 88.
Under the Accessing the LDAP Server section, perform the following steps:
Select Kerberos from the LDAP Server Bind Method drop-down menu.
Click to select the Credential method you want to use.
If choosing Use Public Credentials, type in a username and password.
Remember how you set up the username on the LDP screen. The username
is defined within the device user DN value in the LDP trace and is not in standard
Windows domain account format. The format is often your entire e-mail address,
including the @xx.xx.

here is userPrincipalName instead of mail.

the name, and paste it into the and name using the attribute of field.
