In our case the PDO Oracle driver break kerberos config.
No need to use it, the bug appears when reloading Apache if the PDO Oracle driver is "ON".
Just disabled it.

My Configuration :
- Debian GNU/Linux 6 64-bit
- Oracle Instantclient 11.2
- PHP 5.3.14
- mod_auth_kerb 5.4
- Apache 2.2.16
- Kerberos Heimdal
This can be reproduced using Apache graceful command.
Just after the mod_auth_kerb will fail to read the kerberos conf
gss_import_name() failed: Miscellaneous failure (, Can't open/find Kerberos configuration file.
it will use the same default kerberos configuration as Oracle Database !!!
You can force the path using sqlnet.ora but it will fail after when using gss acquire credential
(unknown error 2 or 21).
We did not find a fix.

I have a similar problem.
mod_auth_kerb works fine as long as I don't use the PHP OCI8 extension. As soon as I load the
OCI8 extension, mod_auth_kerb starts to behave weird. After an Apache (re)start everything is fine,
but when I reload Apache I'm getting in a browser "Internal Server Error" and in the
error log (just like the topic starter):
[Mon Jan 09 14:33:00 2012] [error] [client 10.206.33.199] gss_import_name() failed: Miscellaneous
failure (, Can't open/find Kerberos configuration file)
After stracing the Apache processes it appeared that /krb5/krb.conf is trying to be opened, but
obviously fails on a Linux system. I could prove that Oracle OCI is doing this by setting the
SQLNET.KERBEROS5_CONF parameter to a different value in sqlnet.ora.
So in some way OCI mixes up the Kerberos stuff that mod_auth_kerb is using, but only when Apache is
reloaded. Without everything works perfect, including the PHP OCI8 stuff.
I'm using:
- Debian GNU/Linux 6 64-bit
- Oracle Instantclient Basic 11.2.0.2.0
- PHP 5.3.3 (Debian package rebuild to include OCI8)
- mod_auth_kerb 5.4
- Apache 2.2.16
To create the OCI8 stuff I added the following parameters to the standard Debian PHP build
parameters:
--with-oci8=shared,/usr
--with-pdo-oci=shared,/usr
This is the complete configure command:

The relevant Apache config block:

KrbServiceName HTTP/server1.net@REALM.NET
KrbVerifyKDC On
Require group admins
</Location>
The content on the webserver doesn't matter, Apache breaks before the content can be read, so
it doesn't help to provide a script.
I hope this helps. Do you need anything else?

Description:
------------
Apache server throws internal server error during sso kerberos authentication when php is compiled
with parameter --with-oci8=instantclient,/usr/local/instantclient_11_1/lib
We have currently working apache 2.2.17 server with php 5.2.17 (other versions was also tested)
configured with mit kerberos 5.1.6 and mod_auth_kerb5.4 kerberos module. Before we try to add oci
connection to oracle everything works fine and users was authenticated by sso. After we recompiled
php with oci our apache instance can't load kerberos configuration file and throws internal
server error. It can be related to issue with subprocesses http://bugs.php.net/bug.php?id=9013
I already tried oracle support but they didn't like to help with php.
Expected result:
----------------
Error log without oci (works fine):
[Wed May 11 16:39:54 2011] [debug] src/mod_auth_kerb.c(1628): [client host] kerb_authenticate_user

Actual result:
