 ticket: 6805
 subject: securID code fixes
 target_version: 1.9
 tags: pullup

 Fixes to get securID preauth plugin working. A separate patch will
 address error handling and build issues.

 * Permit a preauth plugin to return KRB5KDC_ERR_PREAUTH_REQUIRED from
   the verify entry point.

 * If verify_securid2 fails, save the return value and return that
   rather than success after dealing with encoding the out_edata

 * Use the client key not the securid principal key for the sam
   checksum

 * indicate that securID is hardware authentication
