[openssl-users] missing default /usr/local/ssl/openssl.cnf causes failure on AIX, warning on all others

(Apologies for the top-post; Outlook does not deal properly with HTML email.)
If open, called by fopen, actually is setting EPERM, then one of the following should be true:
- /usr/local/ssl/openssl.cnf exists but the user does not have read permission on it
- Either /usr/local or /usr/local/ssl exists and is a directory, but the user does not have *execute* permission on it
Note that *read* permission on the directories is not necessary to open a file contained therein. Read permission on a directory is only required to enumerate the directory contents (for ls, find, etc). Execute permission on a directory, on the other hand, is traversal permission, and you need traversal permission along the path to open a file.
There are some other possibilities, such as ACLs (not commonly used in AIX, but available). Users who don't have traverse permission for /usr itself would have a hard time getting this far, so we can probably rule that out.
A run under truss might be enlightening.

Thank you Rich.
The sentence you couldn't understand is my bad, s/b:
"In fact, on some, even non-AIX hosts, permissions would suggest that the permission error should be returned."
