Custom tools? API Quesitons...

[Jason Gerfen <jason.gerfen@scl.utah.edu>]

My question is regarding using the OpenLDAP API's in linux (SuSE 9.0 to 
be exact)

I have created two tools using the LDAP API, one is compiled as a binary 
to do simple searches and the other is a shared object (or PAM module to 
be precise) which also does simple searches.

My problem is that when I test the shared object (or PAM module) it 
fails on the ldap_simple_bind() function.  Below is a snippit of the 
code I am using.  I have tried several methods of binding to the LDAP 
directory in order to search for a username with no luck, any help is 
appreciated....

[Snippit]
static int _ldap_search(udataptr myUser)
{
  LDAP            *ld;
  LDAPMessage     *res, *e;
  int             i;
  char            *a, *dn;
  void            *ptr;
  char            **vals;
  char            buffer[80];
  char            errors[256];
  sprintf(buffer, "(cn=%s)", myUser->usrname);

  /* open a connection */
  if((ld = ldap_init(dflts[7], *dflts[8])) == NULL) {
      _pam_log(LOG_ERR, "Could not initialize connection");
  } else {
      _pam_log(LOG_ERR, "Connection initialized");
      /* authenticate as nobody */
      if(ldap_simple_bind_s(ld, dflts[11], dflts[12]) != LDAP_SUCCESS) 
{ // it fails here
          _pam_log(LOG_ERR, "Couldn't bind to LDAP");
      } else {
          _pam_log(LOG_ERR, "Bind to LDAP successful");
          if(ldap_search_s(ld, dflts[10], LDAP_SCOPE_SUBTREE,
                           buffer, NULL, 0, &res) != LDAP_SUCCESS ) {
              _pam_log(LOG_ERR, "LDAP Search failed");
          } else {
              _pam_log(LOG_ERR, "LDAP Search succeeded"); }
}
[/Snippit]

This is being compiled with the following makefile

Makefile:

CC=gcc
CFLAGS=-fPIC
LDFLAGS=-x --shared
LIBS=-lnsl -lpam -lldap -lc
SRCS=lame.c
OBJS=lame.o
LIBSHARED=pam_looser.so
LIBCONF=looser.conf
SECUREDIRECTORY=/lib/security
CONFDIR=/etc
CONFMODE=700
SECUREMODE=755
INSTALL=install

all: $(LIBSHARED)

install: all
      $(INSTALL) -m $(SECUREMODE) $(LIBSHARED) $(SECUREDIRECTORY);
      $(INSTALL) -m $(CONFMODE) $(LIBCONF) $(CONFDIR);

$(LIBSHARED): $(OBJS)
      $(LD) $(LDFLAGS) -o $@ $? $(LIBS)

$(OBJS): $(SRCS)
      $(CC) $(CFLAGS) -o $@ -c $*.c

clean:
      rm -f $(OBJS) $(LIBSHARED) a.out core *~


I hope someone on this list (tell me if this is the correct list to post 
questions of this type to) that can help me get this working... as I 
said the above code compiled as a shared object (PAM module) will not 
work but it does work when compiled as a simple static binary.
