Uhm, sorry wasn't fast enough for you commit decision but I don't see
that this a dead code? krb5_unparse_string() could return an error so
"else" is a valid condition. I mean it's probably unlikely that
check_for_tgt() returns found and they you can't parse the principal
name out of it. But things like memory errors could still be valid
error conditions?
