Authentication methods for Cloudera Express 6.3 (Cloudera Manager)

Question

Greetings,

I am looking for a way to enforce password complexity requirements, mandatory rotation of passwords and mitigation of brute force password cracking attacks on Cloudera Manager (CM) accounts.

I was researching user authentication options in the free version of CM and came to the conclusion that the only available option is Kerberos and SPNEGO, paired with Kerberos password policies.

In CM I enabled "Enable SPNEGO/Kerberos Authentication for the Admin Console and API", but I didn't notice anything different after restarting the service.

Are there other options (for the free version of CM 6.3) that I am missing? What are the options in the paid version?

Thank you, Kind regards,

Julius

Hi @matagyula ,

Thanks for reaching out to Cloudera community.

Password complexity and account expiration for users in Cloudera Manager is available through external authentication backends. Please note, this need Cloudera Enterprise license.

You can configure external authentication to LDAP/Active Directory or SAML. Read more from below doc:

https://docs.cloudera.com/documentation/enterprise/latest/topics/cm_sg_external_auth.html

However, above does not apply to the CM internal users. We currently have an internal jira which will enhance the validation to the passwords for local CM users adhere to a reasonable policy and it will come in future releases.

Thanks and hope this helps!
