If the function returns an error value, .Fa bad_realm will be set to the realm in the list causing the error. .Fn krb5_check_transited is used internally by the KDC and libkrb5 and should not be called by client applications. .Pp .Fn krb5_check_transited_realms is deprecated. .Pp .Fn krb5_domain_x500_encode and .Fn krb5_domain_x500_decode encodes and decodes the realm names in the X500 format that Kerberos uses to describe the transited realms in krbtgts. .Sh SEE ALSO .Xr krb5 3 , .Xr krb5.conf 5
