1) I have added the group "cloudera_manager_API" in LDAP User Groups. 

 

2) func_svc_zab_cdh is a member of "cloudera_manager_API" group. 

 

3) The configuration.

Re: LDAP/AD authentication failed

@desind,

 

Hi...

 

A couple of things I noticed:

 

(1)

 

Based on the stack trace, you have configured Cloudera Manager's External Authentication with External Authentication Type: Active Directory

 

This means that the username specified in the login page will be concatenated with the Active Directory Domain value to form a userPrincipalName value.

 

For example, if I use a login name of "user1" and my Active Directory Domain is "example.com" the result will be a search for an object that has userPrincipalName=user1@example.com

 

The stack trace shows that the query did not find any such match for that search.

 

If your users' userPrincipalName values do not contain the string they nornally use to log in as (commonly the sAMAccountName) then you will need to use the LDAP value for External Authentication Type in the Cloudera Manager configuration.

 

(2)

 

Based on your screen shot, it appears your LDAP User Search Filter may not be configured in a way that will return any search results.

 

You have:

 

(&(objectclass=user)(memberof:1.2.840.113556.1.4.1941:={0}))

 

 

I don't think that search filter is doing what you want it to do (though I think the issue I mentioned above is causing the direct failure you are seeing now.  When using the LDAP Matching Rule in chain, you would need the {0} to be a group Distinguished Name as mentioned on the following page:

 

https://docs.microsoft.com/en-us/windows/desktop/adsi/search-filter-syntax

 

For example, this may be more in line with what you were intending:

 

(&(objectclass=user)(sAMAccountName={0})(memberof:1.2.840.113556.1.4.1941:=CN=hadoop_group,DC=Example,DC=COM))

 

In the above, only users who are a member of "hadoop_group" or any of the nested groups can auth.

@bgooley

 

1) So when i login into cloudera manager as func_svc_zab_cdh that will be converted to func_svc_zab_cdh@vsp.sas.com 

 

I logged into AD and see the same in the "userPrincipalname" which looks correct. Please find the attachment. 

 

2) Regarding the second point we want to keep it wide open . {0} will be replaced by the username that was used to login screen. 

 

I also tried removing all groups from "LDAP User Groups"  as a test and allowing everyone to login. I , my colleage can login. however "func_svc_zab_cdh" cannot login with the same error. If i enter a wring password for this user i get bad credentials. 

 

I also tried open the search filter to to wide open . event that does not work. 

 

Can you look at maybe debug logs ?

Re: LDAP/AD authentication failed

@desind,

 

The stack shows that whatever search was generated by spring framework didn't return any matches.

You can get more information by enabling TRACE level logging for the springframework classes involved.

 

(1)

 

Edit /etc/cloudera-scm-server/log4j.properties

 

Add the following lines:

 

log4j.logger.org.springframework.ldap=TRACE
log4j.logger.org.springframework.security.ldap=TRACE

 

(2)

 

Restart Cloudera Manager:

 

# service cloudera-scm-server restart

 

-------------------

 

In general, when encountering the problems you describe, I recommend using the "LDAP" External Authentication Type so you have better control over the search filters.

 

I still note that it appears your LDAP User Search Filter is not going to return what you expect since the syntax requires "DN" rather than a username.  The {0} will be replaced with your username, so I don't believe the search will return any users.  The user search filter is only used if you are using the "LDAP" External Authentication so you won't see problems with it unless you do use LDAP (vs Active Directory).

 

Please feel free to share the debug output from a failed login as it should shed light on the problem.  Your UPN does look correct, so it is hard to say why the search is failing to return a result.

Re: LDAP/AD authentication failed

[ Edited ]

After making changes to log4j and removing all entries from LDAP User Search Filter,LDAP User Search Base,LDAP Group Search Filter,LDAP Group Search Base . Which as you said are only used when ldap is present. 

 

In-addition to following this doc : https://www.cloudera.com/documentation/enterprise/5-15-x/topics/cm_sg_external_auth.html using "Active directory" method i found the below 

 

In the Active Directory Domain property, provide the domain to authenticate against.

LDAP URL and Active Directory are the only settings required to allow anyone in Active Directory to log in to Cloudera Manager. 

 

So i just provided LDAP URL and Active directory, after making this change and restarting cloudera-scm-server . I am able to login however "func_svc_zab_cdh"  is not able to login.   

LDAP User Groups - same as screenshot above. 

 

LOGS: 

 

When i login:

func_svc_zab_cdh is like any other user and must be able to login and user is present in the vsp.sas.com domain and in group "cloudera_manager_API"

Re: LDAP/AD authentication failed

@desind,

 

One of the only things I can think of that could have the results you are seeing is if the func_svc_zab_cdh user belongs to another Domain Controller.  You could try looking at the user's LDAP DN as a clue, but if I'm right, you can try using the Global Catalog to see if that allows you and the func_svc_zab_cdh user to authenticate.

 

In your Administration --> Settings search for LDAP URL

 

If you are using ldap, change the port to 3268

If you are using ldaps, change the port to 3269

 

For instance:

change ldap://ad.example.com to ldap://ad.example.com:3268

 

Save the change Restart Cloudera Manager (service cloudera-scm-server restart)

 

Reasoning:

 

- The exception shows that no result was returned for a search for userPrincipalName=func_svc_zab_cdh@vsp.sas.com in the dc=vsp,dc=sas,dc=com subtree

 

- You see in an Active Directory UI that the func_svc_zab_cdh user does have that UPN value

 

- You can log in

 

All these factors seem to indicate that the ldap search just cannot return the user's object.  Global Catalog keeps a copy of user objects that span DCs so if that user is in the domain (which the user appears to be) then a search of the GC may get the results you seek.

Re: LDAP/AD authentication failed

[ Edited ]

I was able to resolve this issue by moving the user and group under one OU. I think most likely it cannot do a backward search. 

 

Thank you @bgooley much appreciated. I learnt a few things in this process.
