HELP: apache + auth_ldap + active directory = [LDAP: ldap_..

Hello Kind Person,

I am trying to use auth_ldap and apache (2.0.5 on a windows machine
to authenticate to a active directory, BUT I am getting the following
error in the log:

[Thu Jul 13 15:09:29 2006] [warn] [client 129.6.84.222] [5224]
auth_ldap authenticate: user kkwiatek authentication failed; URI
/myproject [LDAP: ldap_simple_bind_s() failed][Invalid Credentials]

[Thu Jul 13 15:09:41 2006] [warn] [client 129.6.84.222] [5224]
auth_ldap authenticate: user testbusobj authentication failed; URI
myproject [LDAP: ldap_simple_bind_s() failed][Invalid Credentials]



my httpd.conf looks like :

AuthLDAPURL
ldaps://campus.school.edu:389/dc=campus,dc=school,dc=edu?samAccountName?sub?(objectCategory=person)
AuthLDAPBindDN "CN=myldapuser,dc=campus,dc=school,dc=edu"
AuthLDAPBindPassword abcd1234

I can do the following successfully:
ldifde -f search.ldf -s campus -d dc=campus,dc=school,dc=edu -b
myldapuser domain abcd1234

ANY IDEAS on how to trouble shoot? HOW can I figure out what auth_ldap
is sending to AD?

Thanks,
Keith
