Changes since Citrix Hypervisor 8.2 LTSR

  • The certificate verification feature ensures that all TLS communication endpoints on the management network verify the certificates used to identity their peers before transmitting confidential information. For more information, see Certificate verification.

  • Winbind has replaced PBIS for authenticating Active Directory (AD) users with the AD server and to encrypt communications with the AD server. This replacement happens automatically when you upgrade. In the unlikely case that external authentication does not work after you upgrade to Citrix Hypervisor 8 Cloud, leave the AD domain and rejoin it.

    There are some minor differences in behavior as a result of this change:

    • When using the command xe pool-enable-external-auth to join a domain, the parameter config:disable_modules is now ignored. This parameter is specific to PBIS.
    • For the command xe pool-enable-external-auth, the parameter config:ou now supports either of the following formats when specifying a multiple layer OU: config:ou=a/b/c or config:ou=c,ou=b,ou=a.
    • Winbind automatically updates the machine account password every 14 days or as specified by the configuration option winbind_machine_pwd_timeout.
    • Winbind does not support the following scenarios:

      • Space at the beginning or end of a domain user or domain group name.
      • Domain user names that contain 64 characters or more.
      • Domain user names that include any of the special characters +<>”=/%@:,;\`
      • Domain group names that include any of the special characters ,;\`

    For more information, see Winbind.

  • Changes to guest operating system support.

    The following operating systems are no longer supported:

    • Windows Server 2012 R2
