0x6 - KDC_ERR_C_PRINCIPAL_UNKNOWN Client not found in Kerberos RRS feed

  • Question

  • Hi,

    We encountered an issue with kerberos error: "0x6 - KDC_ERR_C_PRINCIPAL_UNKNOWN Client not found in Kerberos"
    We are using an account system for Open AM, this AD account is used for authentication with AD controler.
    Recently, the silent sso stop working and users were prompted with the sso login page. We found a workaround by generating a new keytab file.

    Unfortunatelay, we know how open AM works but doesn't know how kerberos works. And the issue still continue...
    So, we are looking for a solution, and if possible the way (guide) to implement a troobleshooting of kerberos protocol to identify the source of the problem ?

    Please advise us.
    Thx.
