Kerberos Authentication / Integrated Windows Authentication (IWA) gives the end-user access to Jira without entering username or password. Kerberos requires client machines to have access to a Key Distribution Center (KDC), which in the Windows world generally means Active Directory. For security reasons, AD is generally not reachable outside the local network/corporate intranet, making Kerberos mainly applicable within a company.
In-case you are hosting your Active Directory in a Linux environment, you will need the ktutil tool in-order to generate the keytab. Once you have installed all the necessary packages for this tool, you can use the command given below to generate the keytab. Replace the placeholders in angular brackets with your AD details(without the angular brackets).
addent -password -p
@ -k 1 -e RC4-HMAC
Use the following steps to configure AD.
