Directory Services
What is Directory Services?
A directory service is a system that stores and provides access to information about users, devices, groups, and resources across a network. Unlike a general-purpose database, it is purpose-built for identity and access management: authenticating credentials, controlling access based on group memberships, and replicating data for availability.
When an employee logs in to a workstation or requests access to a SaaS application, the directory verifies identity and determines permissions. Most directories use LDAP as their communication protocol. Common platforms include Active Directory on-premises, Microsoft Entra ID for cloud identity, and vendor-agnostic options like Okta and JumpCloud.
Key takeaways
- Identity Authority: Acts as the source of truth for user identities, group memberships, and access entitlements.
- Protocol vs Product: LDAP is the communication protocol; Active Directory, Okta, and JumpCloud are products that use it.
- Four Core Functions: Authentication, authorization, provisioning, and policy enforcement across connected systems.
- JML Foundation: Powers the Joiner-Mover-Leaver lifecycle that governs onboarding, role changes, and offboarding.
Why Directory Services matters
Directory services determine how quickly a new hire gets access, how securely a departing employee's accounts are deactivated, and how consistently policies hold as people move between roles.
- Eliminates Provisioning Bottlenecks: Group-based application access propagates automatically, removing per-tool ticket filing for every new hire.
- Secure Offboarding: Disabling one directory account revokes access across every connected system at once, closing security gaps before they compound.
- Consistency at Scale: Role-based policies ensure employees in the same role receive identical baseline permissions, preventing ad-hoc access accumulation.
- Audit-Ready Evidence: Directory logs satisfy SOC 2, HIPAA, GDPR, and PCI-DSS requirements on who had access, when, and why.
Directory Services in action
Consider a new marketing hire starting Monday. Without directory automation, HR emails IT, who manually creates accounts in Google Workspace, Slack, and marketing tools. Finance confirms budgets separately, and the hiring manager follows up because design platform access still isn't ready on day one.
With directory integration, the HRIS event creates an identity in Okta, Entra ID, or JumpCloud automatically. Role-based group assignments provision every tool without individual tickets. When the employee is promoted, group memberships adjust to revoke old tools and grant new ones. When they leave, a single deactivation cascades across SSO, SaaS accounts, and device policies with a timestamped audit trail.
How Siit supports Directory Services
Siit sits above your directory as the orchestration layer, turning identity data into automated cross-departmental workflows rather than replacing your existing platform.
- Native IAM Integrations: Connects to Okta, Microsoft Entra ID, JumpCloud, and Google Workspace to sync user, group, and application data automatically.
- 360° Employee Profile: Surfaces role, department, manager, permissions, and device context from the directory so admins act with full context.
- Power Actions: Executes directory changes like group assignments, MFA resets, and application access provisioning directly from Siit without switching panels.
- AI Powered Workflows: Triggers onboarding sequences when HRIS events fire and offboarding checklists when terminations are detected.
- AI Triage: Routes access requests from Slack, Teams, or email to the right team using directory attributes like department and role.
Role-based views keep directory data secure across departments, and integrations with Jira Service Management and Zendesk let teams layer directory-aware automation onto existing systems without a full migration.
