The IWAAC Kerberos SSO add-on is being discontinued as of January 1st, 2021
Following Atlassian's announcement
to put an end to the Atlassian Server product line, we are very sorry to inform our customers that both the IWAAC Kerberos SSO add-on and the ODCC add-on are being discontinued as of January 1st, 2021. There will be no updates to our products from now on but we will answer to support requests until the end of year 2021.
If you use the IWAAC Kerberos SSO add-on and plan to replace your Atlassian Server applications with Atlassian Data Center applications, we recommend that you configure SSO for Atlassian Data Center applications
which is natively provided by Atlassian on its Data Center product line. In that scenario, your users will be redirected to your Identity Provider (e.g. Microsoft Azure AD, Microsoft ADFS, PingIdentity) for Windows Integrated / Kerberos authentication.
If you use the ODDC add-on and plan to replace your Crowd Server with Crowd Data Center, we recommend that you use Crowd's native Azure Active Directory Connector
for user and group management. You may also want to configure Atlassian's native SSO for Atlassian Data Center applications
on each of your Data Center applications for user authentication. In that scenario, your users will be redirected to Azure AD for password or Multi-Factor authentication.
Feel free to contact us at firstname.lastname@example.org
if you have any questions about those recommendations.
