krb5_sname_match - Test whether a principal matches a matching principal.

krb5_boolean krb5_sname_match(krb5_context context, krb5_const_principal matching, krb5_const_principal princ)
param:

[in] context - Library context

[in] matching - Matching principal

[in] princ - Principal to test

return:
  • TRUE if princ matches matching , FALSE otherwise.

If matching is NULL, returnTRUE. If matching is not a matching principal, return the value of krb5_principal_compare(context, matching, princ).

Note

A matching principal is a host-based principal with an empty realm and/or second data component (hostname). Profile configuration may cause the hostname to be ignored even if it is present. A principal matches a matching principal if the former has the same non-empty (and non-ignored) components of the latter.
