ldap apache auth issues

I'm trying to get ldap authentication working in apache. So far I have it connecting and looking up the user in openldap but for some reason it always says mismatched passwd?

So I set my ldap passwd just to make sure:
[root@****** kyle]# ldappasswd -D "cn=root,dc=*******,dc=internal" -W -H ldaps://*******.*******.internal -x "uid=kcorupe,ou=Users,dc=*******,dc=internal"
Enter LDAP Password: 
New password: fecEfe
Result: Success (0)

I see apache connecting to the openldap server:

>>> dnPrettyNormal: <uid=kcorupe,ou=Users,dc=corpedia,dc=internal>
=> ldap_bv2dn(uid=kcorupe,ou=Users,dc=corpedia,dc=internal,0)
<= ldap_bv2dn(uid=kcorupe,ou=Users,dc=corpedia,dc=internal)=0 
=> ldap_dn2bv(272)
<= ldap_dn2bv(uid=kcorupe,ou=Users,dc=corpedia,dc=internal)=0 
=> ldap_dn2bv(272)
<= ldap_dn2bv(uid=kcorupe,ou=users,dc=corpedia,dc=internal)=0 
<<< dnPrettyNormal: <uid=kcorupe,ou=Users,dc=corpedia,dc=internal>, <uid=kcorupe,ou=users,dc=corpedia,dc=internal>
do_bind: version=3 dn="uid=kcorupe,ou=Users,dc=corpedia,dc=internal" method=128
==> bdb_bind: dn: uid=kcorupe,ou=Users,dc=corpedia,dc=internal
send_ldap_result: conn=21 op=2 p=3
send_ldap_result: err=49 matched="" text=""
send_ldap_response: msgid=3 tag=97 err=49
ber_flush: 14 bytes to sd 18
connection_get(18): got connid=21
connection_read(18): checking for input on id=21
ber_get_next: tag 0x30 len 5 contents:
ber_get_next on fd 18 failed errno=0 (Success)
connection_read(18): input error=-2 id=21, closing.
connection_closing: readying conn=21 sd=18 for close
connection_close: deferring conn=21 sd=18
connection_resched: attempting closing conn=21 sd=18
connection_close: conn=21 sd=18

And this is all that I see in error_log for apache, and I have the debug level set:

[Wed May 14 13:05:49 2008] [warn] [client] [13123] auth_ldap authenticate: user kcorupe authentication failed; URI / [ldap_simple_bind_s() to check user credentials failed][Invalid credentials]
[Wed May 14 13:05:49 2008] [error] [client] user kcorupe: authentication failure for "/": Password Mismatch
See, all it says is passwd mismatch, but I am supplying the correct passwd. and it is looking up the correct user in ldap.

Here is my apache config for that section:

<Location "/">
Order deny,allow
Deny from All
AuthName "LDAP Test"
AuthType Basic
AuthBasicProvider ldap
AuthzLDAPAuthoritative on
AuthLDAPUrl ldap://*******.********.internal/ou=Users,dc=corpedia,dc=internal?uid
Require valid-user
Satisfy any

Your Apache config looks OK. Almost certainly LDAP is having trouble. If you bump up the syslog debug level you should be able to see passwords and more detailed LDAP activity (you should have a "debug" log file in your syslog directory - is that where your second listing comes from?). LDAP can be tricky to get going - if you are using LDAP for login authentication check if you can login OK.
