Auth failure with mem client for LDAP user

1. Install CB and configure it to use saslauthd. Create a user in ldap
2. Add user to CB - External user
3. Login to CB Server to make sure that user is authentication correctly with CB. Create a bucket default
4. Using the memcached client, try and do sasl_auth_plain for connection. 

Memcached client returns an auth error. Same works with builtin user.

Code:

from mc_bin_client import MemcachedClient
import uuid

prefix = str(uuid.uuid4())
number_of_items = 10

mc = MemcachedClient(host='10.142.150.101', port=11210)
mc.sasl_auth_plain("ritam","password")
mc.bucket_select('default')

keys = ["

{0}

-

{1}

".format(prefix, i) for i in range(0, number_of_items)]
print ("inserting {0} items".format(number_of_items))
for k in keys:
mc.set(k, 0, 0, str(uuid.uuid4())[0:16])

Output from Test Code:
