Minor bug in error reporting ldap connection on server side

[copumpkin]

    bindErr := ldapServer.Bind(config.LDAP.Bind.DN, config.LDAP.Bind.Password)
    if bindErr != nil {
        log.Error("Could not bind to LDAP! %s", err.Error())

The Bind call is saved to bindErr, but the error message attempts to print err, which at that point will be nil. This leads to a nil pointer dereference error instead of the actual desired error message 😄
