> None of the hosts we've visited have /usr/local/ssl, not to mention the actual default file. ?In fact, on some, even non-AIX hosts, permissions would suggest that the permission should be returned. Not sure what that last sentence means. > Should this be happening? Is AIX simply less forgiving, and returns? a more serious error.?? Or is the openssl CLI handling the missing file differently on AIX? I can well believe that AIX is, exactly that, less forgiving and returns different error codes than many other Unices. There is no AIX-specific code in openssl around file access. Trying "ls -ld" on /usr and /usr/local and /usr/local/ssl and checking errno might be interesting.
