  • Many Unix systems require a slightly different version of Kerberos than what you use with Windows, and the Send Authorization value in the Kerberos SSO profile switches between:

     

    • Always - the KRBv5 mechanism that Windows uses
    • On 401 Status Code - the challenge/response GSSAPI mechanism that most Unix systems use

    See https://support.f5.com/kb/en-us/solutions/public/13000/500/sol13510.html for more information.

     

    If you haven't already, switch to "On 401 Status Code" in the Kerberos SSO profile.
