[users@httpd] Re: Backport of AuthLDAPInitialBindAsUser functionality to 2.2

[Javier Domingo <ja...@gmail.com>]

Covener in #httpd told me to look at config.m4, but I don't really
understand what:

APACHE_MODULE(authnz_ldap, LDAP based authentication, , , no, [
  MOD_AUTHNZ_LDAP_LDADD="`$apu_config --ldap-libs`" || MOD_AUTHNZ_LDAP_LDADD=""
  AC_SUBST(MOD_AUTHNZ_LDAP_LDADD)
])

means. I know I have to put the --ldap-libs option somewhere, but I
can't understand/work out where.

[users@httpd] Re: Backport of AuthLDAPInitialBindAsUser functionality to 2.2

I finally suceeded in compiling the module, and installing it correctly.

The solution was this:

Ldap needs specific linking -lldap -lber -lber. This libs are the libs
the module has to be linked agains. So using the apxs2 script, just:

apxs2 -i -c -Wl, -lldap -lber -lber mod_authnz_ldap.c

Will work.

I would please ask for getting this documented in some way, so that if
someone ever need that once more, knows that he has to look at the
config.m4 and put the output as linking arguments.
