unable to log in using openldap user



Hi,

I need some guidance on setting openldap server and to do
authentication using openldap users.

openldap server: jessie 64-bit
openldap client: jessie 64-bit

ldapsearch test from client to server:

# ldapsearch -h 192.168.191.120 -D cn=admin,dc=test,dc=lab -W -x -b
'dc=test,dc=lab' 'userName=*'
Enter LDAP Password:
# extended LDIF
#
# LDAPv3
# base <dc=test,dc=lab> with scope subtree
# filter: userName=*
# requesting: ALL
#

# search result
search: 2
result: 0 Success


log during log in test with user admin

any help would be appreciated, perhaps there's something really basic
is/are missing
