We can’t consider a new DBMS unless it supports external LDAP authentication. Does cockroach have this feature on the roadmap?
Yes there are plans on the roadmap. We actually want to have some preliminary support prettty soon even. Stay tuned!
As @knz mentioned, support for enterprise authentication mechanisms is indeed on our roadmap. We currently plan to support enterprise authentication via Kerberos/GSSAPI, which should enable integration with most enterprise directory/authentication systems, including Active Directory. Please reach out to me at firstname.lastname@example.org if you’d be interested in learning more, or if you have other requirements you’d like to discuss. Thanks for reaching out!
