Apache Zeppelin - AD integration Version 0.8.2

[#1]

please suggest if anyone has successfully integrated with AD.

I'm trying to use below configs and it's not working 

ldapRealm= org.apache.zeppelin.realm.LdapRealm
ldapRealm.contextFactory.url = ldap://ad.abc.com:389
ldapRealm.contextFactory.authenticationMechanism = simple
ldapRealm.contextFactory.systemUsername = svc_abc
ldapRealm.contextFactory.systemPassword = passwdddd
#ldapRealm.searchBase = DC=abc,DC=abc,DC=COM
ldapRealm.userSearchBase = OU=IDM,DC=abc,DC=abc,DC=com
ldapRealm.userSearchScope = subtree
ldapRealm.userSearchAttributeName = sAMAccountName
ldapRealm.userSearchFilter = (&(objectclass=person)(sAMAccountName={0}))

ldapRealm.authorizationEnabled = true
ldapRealm.groupSearchBase = OU=abcGroups,DC=abc,DC=abc,DC=com
ldapRealm.groupObjectClass = group
ldapRealm.memberAttribute= member
ldapRealm.groupSearchScope = subtree
ldapRealm.groupSearchFilter = (&(objectclass=group)(member={0}))
ldapRealm.memberAttributeValueTemplate= $CN=g_app_zep,OU=abcGroups,DC=abc,DC=abc,DC=com
ldapRealm.groupSearchEnableMatchingRuleInChain = true
ldapRealm.rolesByGroup = Zeppelin_Admin: admin_role
ldapRealm.allowedRolesForAuthentication = admin_role,user_role

ERROR:

please share if there is any working configs

Why this $ before CN?

@BGabor thanks for your response 

I'm trying to understand the difference between two blocks given in the document 

#BLOCK1
activeDirectoryRealm = org.apache.zeppelin.realm.ActiveDirectoryGroupRealm
activeDirectoryRealm.systemUsername = userNameA
activeDirectoryRealm.systemPassword = passwordA
activeDirectoryRealm.searchBase = CN=Users,DC=SOME_GROUP,DC=COMPANY,DC=COM
activeDirectoryRealm.url = ldap://ldap.test.com:389
activeDirectoryRealm.groupRolesMap = "CN=aGroupName,OU=groups,DC=SOME_GROUP,DC=COMPANY,DC=COM":"group1"
activeDirectoryRealm.authorizationCachingEnabled = false
activeDirectoryRealm.principalSuffix = @corp.company.net


##BLOCK2

ldapRealm = org.apache.zeppelin.realm.LdapGroupRealm
# search base for ldap groups (only relevant for LdapGroupRealm):
ldapRealm.contextFactory.environment[ldap.searchBase] = dc=COMPANY,dc=COM
ldapRealm.contextFactory.url = ldap://ldap.test.com:389
ldapRealm.userDnTemplate = uid={0},ou=Users,dc=COMPANY,dc=COM
ldapRealm.contextFactory.authenticationMechanism = simple

also define roles/groups that you want to have in the system, like below;

[roles]
admin = *
hr = *
finance = *
group1 = *

.

could you help me understand?

i want to extract only one group and users from AD, which block should I use. thanks
