Hello,
We are currently trying to get working modXLDAPAuth under an HPUX
B.11.00 machine, using Apache as a webserver, and
tomcat as a servlet engine, with mod_jk2. We are busy implementing
ldap in our systems, and your module seems to be
the only choice on the market for us. After some tries, we managed to
solve every issue except for one, that seems to be
very modXLDAPAuth-specific.
The error given is:
******************************
root@itsv01:/usr/local/mipatsv/apache-2.0.49/bin> ./apachectl startssl
Syntax error on line 56 of
/usr/local/mipatsv/apache-2.0.49/conf/httpd.conf:
Cannot load /usr/local/mipatsv/apache-2.0.49/modules/modXLDAPAuth.sl
into server: Unresolved external
******************************
The configure script run till the end without errors, and it produces
the makefiles.
Other tries with some other modules (mod_auth_ldap module by Muhammad
A. Muquit -- http://www.muquit.com/muquit/software/mod_auth_ldap/mod_auth_ldap_apache2.html
& mod_jk2) configures, compiles & works flawlessy.
Unluckily for us, that modules doesn't handle x509 certificate
requests -- so it isn't an option.
A further investigation by tracing the command with tusc (with "tusc
-f ./apachectl startssl") doesn't produce any useful hint.
Our apachectl looks like this:
******************************
ARGV="$@"
export SHLIB_PATH="/usr/local/mipatsv/apache-2.0.49/modules:/usr/local/mipatsv/apache-2.0.49/src/modXLdapAuth-0.1/openssl-0.9.7d_bin/lib:/usr/local/mipatsv/apache-2.0.49/lib:/usr/local/lib/:$SHLIB_PATH"

******************************
the configure script runs properly, and it doesn't warn about any
possible issues, as I show below:
******************************
./configure --with-apxs=/usr/local/mipatsv/apache-2.0.49/bin/apxs \
--with-ldap-dir=/usr/local \

checking for SSL includes...... yes

======================================================================
You're compiling the module as Dynamic Shared Object (DSO)
Make sure your apache is compiled with DSO support. To test, type
$ /path_of/httpd -l and make sure mod_so.c is in the list
Final Compilation Flags:
APXS = /usr/local/mipatsv/apache-2.0.49/bin/apxs
LDAP_DIR = /usr/local
LDAP_INCLUDE_DIR = /usr/local/include
LDAP_LIB_DIR = /usr/local/lib

CPPFLAGS =

LDFLAGS = -L/usr/local/lib
LIBS = -lldap -llber -lnsl
======================================================================
If everything looks ok, at the shell prompt, type:
make
make install

Ldd complains about some missing references too, but it's still hard
to tell what is missing:
