Problem

Our documentation doesn't properly mention or define RBAC (Role-Based Access Control), which is a key Premium feature for tying templates to groups. When users search our docs for "RBAC", nothing comes up, making this important feature difficult to discover.

Requested Changes

Add comprehensive RBAC-specific documentation that includes:

Core Documentation Tasks

• Explicitly mention and define RBAC and how it fits with other Coder features
• Explain how RBAC interacts or overlaps with IdP sync (or clarify when it doesn't)
• Document how to implement template access controls using RBAC
• Add RBAC terminology and keywords for improved searchability

Content Assessment

Current Documentation Review:

• admin/users/groups-roles: Contains relevant functionality but lacks explicit RBAC terminology and definition
• admin/users/idp-sync: Has some RBAC mentions but could be clearer about the relationship

Content Deficits:

• Missing explicit RBAC definition and conceptual overview
• Lack of searchable RBAC terminology throughout relevant docs
• Unclear relationship between RBAC, groups, roles, and IdP sync
• No dedicated section explaining template access control implementation

Findability Issues:

• RBAC acronym not used consistently in headings or content
• Missing keywords that users would search for
• No cross-references between related RBAC concepts

Acceptance Criteria

• Users searching for "RBAC" can find relevant documentation
• Clear definition of RBAC in Coder context
• Documented relationship between RBAC and IdP features
• Step-by-step guide for implementing template access controls
• Improved keyword coverage for discoverability
