squid authentication against windows Active Directory 2008 ??

[Gregory Machin]

Hi
I'm batteling to  get squid_ldap_auth to authenticate against M$
windows Active Directory 2008 with my config below

/usr/lib64/squid/squid_ldap_auth -b "OU=Organizational
Structure,DC=example,DC=co,DC=za" -h 10.*.*.250 -D
"CN=squid,OU=Other,OU=TC JHB,OU=Company,OU=Organizational
Structure,DC=example,DC=co,DC=za" -w "Password1" -f
"(&(uid=%s)(objectclass=user))"

I have used a similar config on windows Active Directory 2003 and it
worked perfectly fine. Is there a catch to authenticating against the
2008 version of AD ? or have I missed some thing ..

How is the best way to debug this as squid does not log or output any
errors even when in debugging mode ..

when is run
[root at gregory-workstation ~]# /usr/lib64/squid/squid_ldap_auth -b
"OU=Organizational Structure,DC=techconcepts,DC=co,DC=za" -h
10.0.1.250 -D "CN=squid,OU=Other,OU=TC
JHB,OU=Company,OU=Organizational
Structure,DC=techconcepts,DC=co,DC=za" -w "Password1" -f
"(&(uid=%s)(objectclass=user))" -v3
gregory.machin Password1
ERR Success

I get "ERR Success"
I believe I should get "OK"
How can I get more info out of this interface ?

Thanks in advance .
