Jc troubleshoot auth

Troubleshoot JumpCloud Authentication

Systematically diagnose why a user can't log in to JumpCloud or a connected application.

Prerequisites

• jc installed and authenticated (jc auth status)

Gather Information

Ask for:

• Username or email of the affected user (required)
• What they're trying to access (JumpCloud portal, SSO app, LDAP, RADIUS?)
• Error message they're seeing (if any)

Diagnostic Steps

1. Check account status

jc users get USERNAME -t

Look for:

• activated: false = user hasn't activated their account yet
• suspended: true = account is suspended by an admin
• account_locked: true = account is locked (too many failed attempts or manual lock)

If locked: jc users unlock USERNAME If suspended: jc users update USERNAME --suspended false (if appropriate)

2. Check MFA status

From the user get output, check:

• totp_enabled: Is TOTP/MFA configured?
• If MFA is required by auth policy but not set up, the user can't complete login

To reset MFA: jc users reset-mfa USERNAME

3. Check group memberships

jc graph traverse --from user:USERNAME --to user_group -t

If the user is trying to access an SSO app, verify they're in a group that's bound to that app:

jc graph traverse --from user:USERNAME --to application -t

4. Check recent auth events

jc insights query --service all --last 24h --query "[?initiated_by.username=='USERNAME']" -t

Look for:

• sso_auth_failed events — indicates SSO login failures
• user_login_failed — indicates portal login failures
• success: false — any failed operations
• The client_ip field — is the user coming from an expected IP?

5. Simulate auth policies

jc auth-policies simulate --user USERNAME -t

If you know the user's IP:

jc auth-policies simulate --user USERNAME --ip THEIR_IP -t

This shows which conditional access policies would apply and whether they'd allow, deny, or require MFA.

6. Check the specific application (if SSO)

jc apps get APP_NAME -t

Verify:

• The app is active
• The user (or their group) is bound to the app via graph

Common Causes

Symptom	Likely Cause	Fix
"Account not activated"	User never completed activation	Resend activation or reset password
"Account locked"	Too many failed attempts	jc users unlock USERNAME
"Account suspended"	Admin action	jc users update USERNAME --suspended false
"MFA required" but not set up	Auth policy requires MFA	User needs to enroll MFA, or reset with jc users reset-mfa
Can access portal but not app	Missing group/app binding	Check jc graph traverse --from user:USERNAME --to application
Denied by auth policy	IP/location/device restriction	Check jc auth-policies simulate output

Escalation

If the above steps don't identify the issue:

1. Check auth policy blast radius: jc auth-policies blast-radius POLICY_NAME -t
2. Review all org auth policies: jc auth-policies list --all -t
3. Check RADIUS/LDAP config if the user accesses network resources: jc radius list -t / jc ldap list -t
