LDAPError: Invalid Credentials (errCode:49)

[yathav]

I'm getting this error "Invalid Credentials (errCode:49)", when i try to bind with my LDAPServer (which is up and running on my lap, I've verified it using LDPASearch query from terminal).
How can i get this resolved?, what are the ways to debug this issue?

I've double checked that the credentials i pass are right and i'm accessing the directory path that are available.
