How to get LDAP group name by using query or REST API?

[MuS · Accepted solution]

Hi viswanathsd,

try this REST API query:

| rest /services/authentication/providers/LDAP | table "eai:acl.app" groupBaseDN host title

Hi MuS,

Thanks for your speedy response, and currently our [ldap] is the like:

ldap allow_multiple_matching_users 1
ldap max_mem_usage_mb 3000
ldap max_users_to_precache 30000

What I think is the interesting thing here is that when using ldapsearch we can get up till 10,000 rows.

I can't find any other key/values for the [ldap] stanza, do you know of any?

Cheers, Bjarne

Thanks for the direction.
The REST API shows all the referenced AD group names. Is it possible to see the splunk role(s) mapping to each these AD groups?

I found it with the help of your clue. Thank you!

I missed it. Could you document the answer for everyone else? Also, what version of Splunk are you using?

For future reference, since this was never answered, this should work to display roles associated with LDAP groups:

 | rest /servicesNS/nobody/system/admin/LDAP-groups | table title roles | search roles=*

But there is a limit to 1000 groups!
How can that limit be changed or bypassed?

Hi bjarnedein,

this is a two fold issue while you can increase this limit by modifying limits.conf options for the [ldap] stanza to get more results (in theory) you will still hit the server side limit of the LDAP server. You would need to increase both settings to get more results back per query.

Hi,

try the limit=argument with ldapsearch https://docs.splunk.com/Documentation/SA-LdapSearch/latest/User/Theldapsearchcommand but as written before, as long as your LDAP server has a limit of 1000 (default for most of the LDAP implementations) you will not be able to retrieve more results.

cheers, MuS
