# krb5_pac_sign_ext - Sign a PAC, possibly with a specified realm.

krb5_error_code krb5_pac_sign_ext(krb5_context context, krb5_pac pac, krb5_timestamp authtime, krb5_const_principal principal, const krb5_keyblock *server_key, const krb5_keyblock *privsvr_key, krb5_boolean with_realm, krb5_data *data)

param

  [in] context - Library context

  [in] pac - PAC handle

  [in] authtime - Expected timestamp

  [in] principal - Principal name (or NULL)

  [in] server_key - Key for server checksum

  [in] privsvr_key - Key for KDC checksum

  [in] with_realm - If true, include the realm of principal

  [out] data - Signed PAC encoding

This function is similar to `krb5_pac_sign()` , but adds a parameter with_realm . If with_realm is true, the PAC_CLIENT_INFO field of the signed PAC will include the realm of principal as well as the name. This flag is necessary to generate PACs for cross-realm S4U2Self referrals.
