Need to BIND USERS FROM WINDOWS 2003 through LDAP

Dear all,

I need to do squid configuration thrugh LDAP. For that I need to bind the users from windows 2003. I am getting an error while LDAP configuration.
“A problem occured while reading schema from LDAP server.
DSID: 0c090627, In order to perform this operation a successfull bind must be completed on the connection, data 0.”
How to bind the users from linux.

Thanks and Regards,
Rakesh
