Subject RE: [users@httpd] apache 2.2 - mod_authnz_ldap with SSL/TLS in chrootdir
Date Thu, 03 Nov 2016 10:26:40 GMT
I think this might be a bug , i’ve also tested , even copied almost all the system files
in the chrootdir but dint’ change anything.

TLS or SSL doesn’t work  but LDAP unencrypted does.

Subject: Re: [users@httpd] apache 2.2 - mod_authnz_ldap with SSL/TLS in chrootdir

 

Hi Andy,

Hi Folks,

 

I’m having some issues getting SSL or TLS working with mod_authnz_ldap in my chroot’ed
Apache 2.2 server on RHEL 6.8 … it works without SSL just fine.  I’m using the built-in
“ChrootDir” directive with Apache.  I seem to have all of the libraries, binaries and
things in the chroot jail that Apache uses… but, I can’t seem to get it to work… and
I kinda need to know how best to troubleshoot this to figure out where the problem lies.

 

Inside and outside the chroot jail I can use ldapsearch with SSL just fine… so, I know the
system can connect… I’m just getting tripped up on why Apache can’t connect.  I get
this very generic error in the logs:

 

[LDAP: ldap_simple_bind_s() failed][Can't contact LDAP server]

 

I have the global loglevel set to debug… but, this really isn’t giving me much insight
into the mod_authnz_ldap internals.  Can that be turned up?

 

Any help would be appreciated.

 

 

(just to have more info) have you followed https://httpd.apache.org/docs/2.2/mod/mod_authnz_ldap.html#usingssl
setting all the required directives? 

 

What I'd try: 

1) Same config without the ChrootDir to see if anything changes.

2) A recent 2.4 version and Loglevel set to trace8.

3) GDB might help (https://httpd.apache.org/dev/debugging.html#gdb) but it requires digging
into the source code.

 

If you want more people to help you could also send us the whole httpd configuration plus
what you see in the error logs (not only the line reported above).

 

Hope that helps!

 

Luca
