CAD file check-in fails with permission denied error in IP management module

We’re experiencing a critical issue where CAD designers cannot check in files to the IP management vault. The error message shows ‘Permission Denied - Insufficient vault access rights’ when attempting to check in assemblies.

This started after our recent LDAP group synchronization update. The vault ACL configuration appears correct in the admin interface, but role-based access control inheritance seems broken. We’ve verified that users belong to the correct LDAP groups (CAD_DESIGNERS, IP_CONTRIBUTORS), but permissions aren’t propagating properly.

Users have tried clearing their client cache multiple times, but the issue persists. The same files check in successfully to standard product folders, so it’s specifically related to IP management vault permissions. This is blocking our entire design workflow for protected IP assets.

Has anyone encountered similar vault ACL inheritance issues after LDAP updates?

That AD restructuring is your smoking gun. When LDAP distinguished names change format, Windchill’s group mappings break even though the sync appears successful. Here’s the complete resolution:

1. Vault ACL Configuration Review: First, verify your vault ACL rules reference groups by name, not by DN. In the IP Management vault properties, check that access rules use group names (CAD_DESIGNERS) rather than full distinguished names. This makes them resilient to AD structural changes.

2. Role-Based Access Control Inheritance Fix: The inheritance chain broke because parent container ACLs still reference old DNs. You need to:

  • Navigate to the IP Management root container
  • Edit security policies and re-select the LDAP groups from the picker (this updates internal DN references)
  • Enable ‘Propagate to child objects’ to cascade corrected ACLs downward

3. LDAP Group Synchronization Repair: Run this administrative command to force DN remapping:


windchill wt.ldap.SyncLDAPGroups -refresh -updateDN
windchill wt.access.RefreshACLCache -context /wt.inf.container.IPManagement

The -updateDN flag tells the sync job to update stored distinguished names to match current AD structure. Follow with the ACL cache refresh for the IP Management context specifically.

4. Client Cache Clearing (Comprehensive): Standard cache clearing isn’t enough. Users need to:

  • Close all CAD applications and Windchill clients
  • Delete the entire workspace cache directory (not just clear from UI)
  • Delete credential cache: C:\Users[username]\AppData\Local\PTC\auth_cache
  • Restart and re-authenticate

5. Verification Steps:

  • Test vault access through web UI first to confirm server-side fix
  • Check ACL effective permissions for a test user (Site > Utilities > Policy Administrator)
  • Monitor MethodServer logs during check-in attempt for any remaining ACL resolution errors

Prevention: Set up monitoring for LDAP DN format changes. Configure Windchill to use group names with automatic DN resolution rather than hardcoded DNs in ACL rules. This makes your system resilient to future AD reorganizations.

The combination of DN remapping + ACL propagation + comprehensive cache clearing should resolve your permission issues. The entire process typically takes 2-3 hours including verification testing.

I’ve seen this exact behavior. The LDAP sync can sometimes create a mismatch between external group memberships and Windchill’s internal ACL cache. Even though the admin UI shows correct permissions, the runtime ACL resolver might be using stale data.

First diagnostic step - check if the issue is user-specific or group-wide. Have one affected user try accessing the vault through the web interface instead of the CAD client. If web access works but CAD client fails, it’s a client-side cache issue beyond just clearing workspace cache.

Check your wvs.properties configuration file on the vault server. After LDAP synchronization, the vault service needs to refresh its ACL mappings. Look for these settings:


wvs.acl.cache.refresh=300000
wvs.ldap.sync.interval=3600000
wvs.acl.inheritance.enabled=true

If the cache refresh interval is too long, vault ACLs won’t update even after successful LDAP sync. Also verify that ACL inheritance is explicitly enabled - it can get disabled during upgrades.

The ‘Permission Denied’ error in IP management is often related to context-specific security policies. IP vaults typically have stricter access rules than standard vaults. When LDAP groups sync, the security label assignments might not transfer correctly to the IP context.

Run this query to verify group-to-security-label mappings are intact. Look specifically for entries where the IP_VAULT context shows null or incorrect security labels for your CAD_DESIGNERS group.

I encountered this on a 11.1 M030 implementation last year. The root cause was that the LDAP synchronization job completed successfully, but the vault ACL propagation task failed silently. You need to manually trigger the ACL recalculation for the IP management container.

Navigate to Site > Utilities > Server Management and look for the ‘Recalculate Access Control’ task. Run it specifically for the IP Management context. This forces Windchill to rebuild all ACL entries based on current LDAP group memberships. The task can take 30-60 minutes depending on your data volume.

Confirmed this resolves the issue — after switching vault ACL rules in IP Management from DN-based to group-name references like CAD_DESIGNERS, our Windchill check-ins succeeded immediately post-AD restructure.

Thanks for all the suggestions. We ran the ACL recalculation task as suggested, but the issue persisted. We then discovered that our LDAP group distinguished names had changed format during a recent Active Directory restructuring (moved from flat structure to OU-based hierarchy).
