Zeppelin security : Issues while securing Zeppelin UI

Expert Contributor

HDP-2.4.2.0-258 installed using Ambari 2.2.2.0

I installed Zeppelin(0.6.0.2.4.2.0-258)manually and was able to execute several paragraphs in a notebook.

Now I wish to secure it step-by-step, starting with the authentication for the web UI, integrated with LDAP i.e when a user enters his credentials after hitting http://<zeppelin_server_hostname>:9995/, he can proceed only if he is present in at least one of the several Unix LDAP groups as follows :

devdatalakeadm

datascientist

developer

I tried the ways mentioned in the Hortonworks article, Hortonworks Zeppelin tutorial, Apache Zeppelin doc. etc. but getting some or the other error, currently, I am focusing on just one LDAP group.

For the ldapRealm, if I provide org.apache.zeppelin.server.LdapGroupRealm, I get the following error and Zeppelin fails to start

If I use org.apache.shiro.realm.ldap.JndiLdapRealm,

  • Zeppelin starts successfully
  • When accessing http://<zeppelin_server_hostname>:9995/, I get an username password prompt in the browser
  • I enter my credentials and probably the log-in fails as the window reappears
  • If I cancel instead of entering the username and password, I get the Zeppelin UI(that's crazy !)

The error :

********************EDIT-1 : New Zeppelin version(zeppelin-0.6.1-bin-all.tgz)********************

I am running the new version on the same machine as Ambari and the existing/older Zeppelin version.

The shiro.ini file, please note the following :

  • I have entirely commented the [users] and [roles]
  • For 'ldapRealm.userDnTemplate', it's immaterial whether I use uid={0} or CN={0}
  • I'm assuming(as per the original requirement) that the group where the provided credentials must be searched is provided as a value to 'ldapRealm.userDnTemplate'. Is it that the LDAP groups must have a different key ?

I now wonder if ldap is behaving itself, following is the output of two commands that makes me believe that ldap is NOT able to check if a particular user, say ojoqcu, belongs to a ldap group :

If I query just for the user, all his membership groups are returned :

ldapsearch -h unix-ldap.company.com -p 389 -x -b "dc=company,dc=SE" "(&(cn=*)(memberUid=ojoqcu))"
# extended LDIF
#
# LDAPv3
# base <dc=company,dc=SE> with scope subtree
# filter: (&(cn=*)(memberUid=ojoqcu))
# requesting: ALL

# numEntries: 2

but if I try to check if the user is part of group, no entries returned :

ldapsearch -h unix-ldap.company.com -p 389 -x -b "dc=company,dc=SE" "(&(cn=devdatalakeadm,ou=Group,dc=company,dc=se)(memberUid=ojoqcu))"
# extended LDIF
#
# LDAPv3
# base <dc=company,dc=SE> with scope subtree
# filter: (&(cn=devdatalakeadm,ou=Group,dc=company,dc=se)(memberUid=ojoqcu))
# requesting: ALL
#
# search result
search: 2
result: 0 Success
# numResponses: 1

What could be the root cause ?

Re: Zeppelin security : Issues while securing Zeppelin UI

1) What could be the root cause ?

I think it's just the wrong ldapsearch filter, should be ldapsearch -h unix-ldap.company.com -p 389-x -b "dc=company,dc=SE""(&(cn=devdatalakeadm)(memberUid=ojoqcu))"

cn=devdatalakeadm,ou=Group,dc=company,dc=se is actually the full dn and you cannot search on it as it's not an attribute.

2) Your problem is still the userDnTemplate, that's why you're still getting the LDAP authentication exception

ldapRealm.userDnTemplate = uid={0},cn=devdatalakeadm,ou=Group,dc=company,dc=se

Why are you trying to search the user inside the cn=devdatalakeadm subtree?

That's not how users and groups are represented in LDAP (unless you did something very specific).

Users and Groups are normally in separate trees and membership is only decided by the memberUid parameter in your case.

But if memberUid is ojoqcu it doesn't mean uid=ojoqcu,cn=devdatalakeadm,ou=Group,dc=company,dc=se actually exist, ojoqcu user could be in a separate tree/ou, like uid=ojoqcu,ou=User,dc=company,dc=se

To further help you finding out the correct userDnTemplate, I'd need an ldapsearch output for a user, just like you showed for groups.

@Kaliyug Antagonist HDP 2.4.0 has Zeppelin Tech Preview only, this issue can not be found in Zeppelin with HDP 2.5.0 which is the version officially supported.

Yeah I read about that but does that mean that with HDP 2.4, Zeppelin cannot be secured in the way I am trying to ? Can Hue or some other component help ?

Re: Zeppelin security : Issues while securing Zeppelin UI

You should really install a newer Zeppelin version as there have been quite a few changes and enhancements in terms of security. I wouldn't advise trying security with that old Zeppelin version.

The 0.6.0.2.4.2.0-258 from the HDP2.4.2 repo doesn't come with the org.apache.zeppelin.server.LdapGroupRealm class so you won't be able to use it (the error you receive is absolutely normal).

If you don't want to upgrade to HDP2.5 you can at least manually compile 0.6.2 from https://github.com/apache/zeppelin/tree/branch-0.6:

git clone https://github.com/apache/zeppelin.git -b branch-0.6 
cd zeppelin/ 
mvn clean package -DskipTests -Pspark-1.6 -Phadoop-2.6 -Dhadoop.version=2.7.1 

If you get the UI when you cancel the login, that's probably because anonymous is still allowed, so set zeppelin.anonymous.allowed to false in conf/zeppelin-site.xml

Lastly, as a curiosity, I tried 0.6.0.2.4.2.0-258 from HDP2.4.2 with ldapRealm = org.apache.shiro.realm.ldap.JndiLdapRealm and it works just fine, even if I sometimes get the Invalid ticket error in the logs.

Your LDAP layout might be different and the shiro config wrong.

Are you sure the userDN is uid={0} and not CN={0}?

Are you sure the users are in the ou=Group,dc=company,dc=SE baseDN?

Usually groups are just other entries in the LDAP and the group membership is controlled by member attribute rather than putting users in Group subtrees.

For now, I wish to continue with the existing versions but I will try the Zeppelin 0.6.2.

Well, I discovered several facts :

  1. On canceling the log-in, the UI is seen but it shows a 'Login' button on the top right corner
  2. I had NOT created any conf/zeppelin-site.xml, a template file exists there, though
  3. I tried using ldapRealm.userDnTemplate=CN={0},CN=devadmin,ou=Group,dc=company,dc=SE but the same result

Is there any way the exact cause/error can be captured(the Zeppelin log errors I have already provided) ?

Re: Zeppelin security : Issues while securing Zeppelin UI

1. Yes, this means anonymous has been allowed access

2. make a copy cp conf/zeppelin-site.xml.template conf/zeppelin-site.xml, edit the file and set that variable to false

3. When I put the wrong userDnTemplate, I get the following, so it's something to look for in the logs:

LoginRestApi.java[postLogin]:99) - Exception in login:
org.apache.shiro.authc.AuthenticationException: Authentication token of type [class org.apache.shiro.authc.UsernamePasswordToken] could not be authenticated by any configured realms.  Please ensure that at least one realm can authenticate these tokens.

But really, you should get the right LDAP template, it might not be a problem with CN or uid, but a problem with the path (for example, the user might be in ldapRealm.userDnTemplate=CN={0},ou=Users,dc=company,dc=SE, not ou=Group,dc=company,dc=SE)

How do you use this LDAP in other projects / apps?

Run ldapsearch on it:

ldapsearch -h unix-ldap.company.com -p 389 -x -b "dc=company,dc=SE"

(although you might not be allowed to bind anonymously).

Ask your LDAP admin, etc

Good luck!
