krb5_error_code `krb5_rd_cred`(krb5_context context, krb5_auth_context auth_context, krb5_data * creddata, krb5_creds *** creds_out, krb5_replay_data * rdata_out)

param: | [in] context - Library context [in] auth_context - Authentication context [in] creddata - KRB-CRED message [out] creds_out - Null-terminated array of forwarded credentials [out] rdata_out - Replay data (NULL if not needed)

retval: | 0 Success; otherwise - Kerberos error codes

> creddata will be decrypted using the receiving subkey if it is present in auth_context , or the session key if the receiving subkey is not present or fails to decrypt the message.

Use `krb5_free_tgt_creds()` to free creds_out when it is no longer needed.

Note

The rdata_out argument is required if the `KRB5_AUTH_CONTEXT_RET_TIME` or `KRB5_AUTH_CONTEXT_RET_SEQUENCE` flag is set in auth_context .`
