Re: LDAP over SSL on Slaris Sparc 5.10 (Apache Users)

Based on this https://bz.apache.org/bugzilla/show_bug.cgi?id=41041 I decided to hard code some CPP and LD flags for the configure/make steps:

# Force the apr builds to find libs here and at run time load them from here.
CPPFLAGS='-I/opt/csw/include'
export CPPFLAGS
LDFLAGS='-R/opt/csw/lib -L/opt/csw/lib'
export LDFLAGS

This now gives me one nice new line in the error log and then the one that is not so nice:

[Thu Jun 16 16:28:48.191774 2016] [ldap:info] [pid 8328] AH01318: APR LDAP: Built with OpenLDAP LDAP SDK
[Thu Jun 16 16:28:48.192275 2016] [ldap:info] [pid 8328] AH01320: LDAP: SSL support unavailable: (null)

What causes httpd runtime to spit out that "support unavailable" message?

openssl is there, it is linked into the modules, the command line tools can connect to my AD server.

The only thing I can think of is that either my openssl package is too new (tls support dropped in 1.0.0t??) or that the openldap package (2.4.40) I have is not compatible (built) with this version of openssl.

So I am going to try to build openldap and openssl now.

Anyone know which newish versions work well together?

I am trying to build apache httpd 2.4.20 with LDAP over SSL support

No matter what I try I always get this as the first line in the error log file at start up:

[Wed Jun 15 19:26:17.222691 2016] [ldap:info] [pid 27064] AH01320: LDAP: SSL support unavailable

I believe (through many hours or perseverance) I am using the correct configure cmdline args which should enable the httpd/apr/apr-util build to find:

openssl (latest from installed csw package)

openldap (latest from installed csw package)

apr 1.5.2 (from src build with httpd)

apr-util 1.5.4 (from src build with httpd)

pcre 8.36 (built and installed to /opt/pcre)

My configure runs without errors and with no LDAP or SSL warnings.

My make runs without error.

My install runs without error.

Httpd boots.

With LogLevel set to "trace8" here is what I get on the command line:

$ sudo ./apachectl start

When trying to contact the server through a browser I am prompted for login/passwd.

If I used an NIS account (validated through local passwd/group files) it authenticates fine.

If I use an Active Directory (non-NIS) account it tries LDAP and this fails with errors in the error_log like:

The configuration for the directory I am trying to browse to is:

    Options Indexes FollowSymLinks MultiViews Includes
    AuthName "Use NIS or Active Directory Login"
    AllowOverride None
    LDAPReferrals Off
    AuthType Basic

    AuthLDAPBindDN CN=aduserforread,OU=Engineering,DC=global,DC=corp,DC=markco
    AuthLDAPBindPassword FakePassW0rd
    Require valid-user

I have confirmed I can use the "ldapsearch" commandline tool from openldap with these values to query AD successfully.

Any thoughts on what I can do to make LDAP over SSL work?

Thanks
