krb5_pac_verify_ext - Verify a PAC, possibly from a specified realm.

krb5_error_code krb5_pac_verify_ext(krb5_context context, const krb5_pac pac, krb5_timestamp authtime, krb5_const_principal principal, const krb5_keyblock * server, const krb5_keyblock * privsvr, krb5_boolean with_realm)
param:

[in] context - Library context

[in] pac - PAC handle

[in] authtime - Expected timestamp

[in] principal - Expected principal name (or NULL)

[in] server - Key to validate server checksum (or NULL)

[in] privsvr - Key to validate KDC checksum (or NULL)

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

This function is similar to krb5_pac_verify() , but adds a parameter with_realm . If with_realm is true, the PAC_CLIENT_INFO field is expected to include the realm of principal as well as the name. This flag is necessary to verify PACs in cross-realm S4U2Self referral TGTs.
