C:\WINDOWS\system32>kinit xx@yyy.COM
Password for xx@yyy.COM:

==========
And I have tried with this command
#telnet kerberos.example.com 88
Getting this error
connecting to mapr\xxx.yyy.com@YYY.COM..........could not open connection to the host on port 88 : connect failed.
===========
And also suggest me how to establish the connection between the windows client and KDC server
=========================
And also share the specific script to configure the MIT kerberos for windows.
