-Status: Bogus
+Status: Open
Bug Type: LDAP related
Operating System: RedHat Linux 7.3
PHP Version: 4.3.4
New Comment:
Is it possible that a different change effected the calls to ext/ldap
function callings?
I don't know.
All I know is, the only variable here is the version of php, nothing
else changes on the server.
So from a test viewpoint, if the only variable causes a malfunction,
that variable, when changed, must be the catalyst.
Of course this is code, so any number of things in that version could
be causing the problem.
All I know is:
1) All previous versions work.
2) LDAP version did not change and is current.
3) Same result with Oracle support built in or left out.
4) Current version of ext/ldap has not changed.
5) NOTHING else has changed on the server.
6) Using 4.3.4 results in a SEG FAULT
The cause? Unclear.
You have suggest it is an ldap bug, so I will submit a bug to them as
well.
I copied the ext/ldap from 4.3.2-RC to 4.3.4 and built on those, it
built, worked, and still seg faulted, so, my only thought is whatever
is making the calls to the ldap functions or making use of the api is
causing the seg fault.
I may very well be wrong, but I am trying to track down a problem and
not getting very much assistance.
I will keep at this anyway. Hopefully if others are having the same
issue they report it.
I am using server: Apache/1.3.27
I am using: Server API Apache
I am using SSL for the ldap connection:
ldaps://
Could it be something to do with the SSL?

If you don't believe me, fine, but there aren't any changes in ext/ldap
between PHP 4.3.1 -> 4.3.4 that could cause this crash.

Just explain one last thing then,,,
Why does it work with all previous versions of php, but not this
version if it is indeed in the libs and not php?
If the bug was indeed in the ldap libs and not php, wouldn't it not
function in previous versions?
I will just go back to version 4.3.2-rc and use that. After all, THAT
version of PHP works fine with this same 'supposed' bugged version of
openldap.

It crashes inside the ldap libs -> Not PHP bug. (report to openldap
folks)

Try compile PHP without --with-oci8 altogether. And use the openldap
libs intstead for --with-ldap so we know for sure this really is caused
by oracle..
