Set up Privileged Identity Management: activate admin rights only when needed

How can Microsoft Entra Administrator rights be provided only for the actual period of use? With Microsoft Entra Privileged Identity Management, short PIM, supported roles can be set up as eligible assignments. The user does not have the role constantly active, but activates it as needed for a limited duration. Depending on the configuration, MFA, justification, ticket number, Conditional Access, or approval can be required.

PIM reduces permanently active privileges. However, it does not replace a role model or emergency access. A role that is too broad remains too broad even if it is active for only two hours. Therefore, tasks, roles, activation duration, approvers, monitoring, and fallback paths must be defined before implementation.

Understand active, eligible, and expiring assignments

Status: Active

Meaning: Role is effective without additional activation

Typical Use: few necessary permanent functions

Status: Eligible

Meaning: User may activate the role as needed

Typical Use: normal privileged administration

Status: Time-bound active

Meaning: Role is active only within a defined period

Typical Use: project or transition

Status: Time-bound eligible

Meaning: Activation authorization has an expiration date

Typical Use: temporary task or external access

PIM does not manage every conceivable permission in the Microsoft ecosystem. Supported are in particular Microsoft Entra roles, numerous Azure roles, and PIM for Groups. For the specific role, resource, and license, current support must be checked.

Prerequisites before PIM implementation

1. Check license and scope

For PIM, license requirements must be clarified before the pilot. PIM is assessed under Microsoft Entra ID Governance; which users need a license depends on the scenario, the role, involved reviewers, approvers, and possibly PIM-for-Groups processes. This assignment should be documented before the pilot, rather than clarified only at the first activation.

2. Clean up role inventory

PIM should not simply be placed over an unclear role inventory. First, capture:

• all permanently active roles,
• all Global Administrators,
• external and guest administrators,
• Assign roles through groups,
• Assign roles with Azure resource scope,
• Define the business task and responsible person,
• Review past usage and designate a substitute.

After this, decide which assignments to remove, reduce, set a time limit for, or convert to eligible.

3. Ensure emergency accounts

Emergency access accounts must not depend on a PIM process that could itself be disrupted. They require a separately documented and regularly tested access. Details are described in Emergency access for Microsoft 365.

Define activation rules per role

PIM settings should not be uniformly the same across the entire tenant. The risk associated with a role determines the activation requirements.

Activation duration

A reasonable duration is long enough for the task and short enough to avoid unnecessary exposure. Examples:

• Helpdesk-related role: short activation for individual cases,
• Exchange or SharePoint administration: a few hours for maintenance windows,
• Global Administrator or Privileged Role Administrator: as short as possible, with particularly controlled activation.

Time limits that are too short lead to repeated activations during ongoing work. Time limits that are too long weaken the just-in-time effect.

MFA during activation

MFA during role activation ensures that an existing session alone is not sufficient. For highly privileged roles, phishing-resistant methods and appropriate authentication strengths should be checked. The concrete effect depends on authentication, Conditional Access, and PIM configuration.

Justification and ticket number

A justification creates context, but is only useful if it is verifiable. Free-text entries like "Admin task" are not enough. Better options are:

• Change or ticket ID,
• Target system,
• Planned activity,
• Expected duration.

Approval

PIM can make activation dependent on one or more approvers. Microsoft documents that requests not approved in time expire and must be resubmitted. Therefore, an approval model requires designees and an emergency path.

Appropriate questions:

• Who understands the risk of the role?
• Who is reachable during operating hours?
• Can the same approver also approve the change?
• What happens in the event of absence?
• Which roles may be activated without approval because an immediate response is necessary?

Notifications

Configure alerts for activations, assignment changes, and critical roles. Notifications should go to monitored addresses, not just to individual people. An email does not replace an audit but supports rapid detection.

PIM for groups

PIM for Groups can activate membership or ownership of a group over time. This is useful when a group in turn grants access to applications, Azure resources, or Entra roles.

In this case, the entire path must be considered:

Benutzer → PIM-Gruppenmitgliedschaft → Gruppenberechtigung → Zielressource

Check:

• which permissions the group actually grants,
• whether nested groups are involved,
• whether membership and ownership are separated,
• how quickly activation and deactivation propagate to target systems,
• whether the target application evaluates group assignments directly.

Implementation plan in seven steps

1. Select pilot roles

Start with a few roles whose tasks are clear. Avoid a simultaneous overhaul of all privileged access.

2. Name pilot participants and approvers

Use real administrators but keep active fallback rights ready. Document designees.

3. Configure activation rules

Set duration, MFA, justification, ticket, approval, and notification.

4. Run positive and negative tests

Verify that the authorized role can be activated and that the same administrative action fails without activation.

5. Monitor propagation time

Microsoft notes that activations do not have to be visible immediately in every portal. Test the admin centers and APIs actually used.

6. Remove permanent assignment

Only after a successful pilot is the previously active role removed or made temporary. Then check existing sessions and tokens.

7. Establish operations and review

Monitor activations, expiring permissions, role setting changes, and unusual usage.

Typical failure patterns

Role is eligible but activation is not possible

Possible causes:

• Activation authorization has expired,
• Required MFA method is missing,
• Conditional Access is blocking,
• Approver is unavailable,
• User is in the wrong tenant,
• Role applies to a different scope,
• License or PIM configuration does not cover the scenario.

Test: Check PIM assignment, scope, activation requirement, login log, and approval status individually.

Role was activated but portal still shows missing rights

Possible causes are propagation delay, an old token, or the wrong role. The user should check the activation confirmation, renew the session, and compare the specific role description. A blanket additional Global Admin assignment obscures the cause.

Approval request remains stuck

Approvers may be unavailable or overlook notifications. PIM requests are not indefinitely open. Therefore, multiple suitable approvers, operating hours, and a documented escalation path are required.

Eligible and active assignments exist in parallel

In this case, PIM appears to be functioning, but the role is permanently active anyway. The role inventory must be reviewed after migration.

Role expires during a change

An expired role does not necessarily terminate any already started operation immediately, but it prevents further administrative steps. Maintenance work should be scheduled within the activation duration. For longer tasks, a justified longer activation or reactivation may be necessary.

Fallback paths

PIM or approval path unavailable

• use your own emergency access account,
• document the incident,
• assign the necessary minimal role for a limited time,
• remove the special assignment after restoration,
• review the cause and logs.

Wrong role activated

• end the active assignment in PIM,
• revoke sessions at risk,
• review the audit log,
• review the affected changes,
• correct the role setting or permission.

Approver structure flawed

• appoint a substitute,
• do not assign a permanent broad role as the standard fallback,
• adjust the approver list and availability,
• run the test again.

Monitoring and reviews

Regularly check the following:

• Activations of high-privilege roles,
• Activations outside expected times,
• Repeatedly rejected or aborted requests,
• Changes to PIM role settings,
• New permanently active assignments,
• Authorized assignments without usage,
• Expiring permissions,
• Approvers without a substitute.

Access Reviews can support the regular review of certain privileged assignments. The business purpose must still be confirmed. See Access Reviews in Microsoft Entra ID for more information.

Acceptance test for production PIM

1. Authorized user sees the correct role.
2. Activation requires the intended controls.
3. Approver receives and processes the request.
4. Allowed admin task functions after activation.
5. Unauthorized task remains blocked.
6. Activation appears in Audit and PIM history.
7. Role expires after the configured time.
8. Target portal recognizes revocation after an appropriate session refresh.
9. Substitute can approve.
10. Emergency Access functions independently.

Before a broad PIM implementation, it is worthwhile to establish the business foundation from Administrator roles in Microsoft Entra ID. For recurring confirmations of privileged permissions, Access Reviews in Microsoft Entra ID are suitable afterward.

How privileged rights are time-limited yet still available

PIM is effective when it complements a reviewed role model. Authorized instead of permanently active assignments, appropriate activation times, strong authentication, reliable approvers, and consistent monitoring reduce standing privileges. Tested emergency accounts simultaneously ensure that the organization is not locked out by its own control mechanism in the event of a disruption.
