ERROR_PER_USER_TRUST_QUOTA_EXCEEDED

The current user exceeded the delegated trust creation quota.

ERROR_PER_USER_TRUST_QUOTA_EXCEEDED is Win32 error 1932 (0x78C). It is an administrative limit on delegated creation of trust relationships by the current identity. The failure is specific to that user or delegated principal; it does not by itself prove that the directory-wide creation capacity is exhausted.

Why the per-user limit is reached

  • automation repeatedly creates test or temporary trusts under the same delegated account
  • failed workflows leave trust objects that are not reconciled or retired
  • several management systems share one delegated credential and consume its allowance collectively
  • an operator is using delegated rights where a controlled higher-privilege workflow was intended
  • the request is targeting the wrong forest or domain and counting against an unexpected administrative boundary

Administrative evidence

Record the requesting identity SID, source management system, local and partner domains, trust direction/type requested, change ticket, domain controller, existing trust inventory, and result code. Protect trust names and topology as administrative data, and never record trust passwords or secret material. Correlate attempts across tools that may use the same service account.

Diagnostic sequence

Confirm that the failure is 1932 rather than the total quota code 1933. Inventory trust objects created or owned through the delegated workflow and determine whether abandoned lab, migration, or tenant relationships remain. Verify the target domain and the caller actually used for the directory operation.

Review the delegation design before elevating privileges. A quota can be functioning as intended by containing an account or buggy automation. Identify the documented trust lifecycle and whether deletion is permitted under the same delegation.

Resolution and governance

Remove obsolete trusts through approved procedures, correct automation leaks, or execute the justified creation through a separately controlled administrative identity. Do not bypass the quota simply by cycling among shared accounts; that hides ownership and weakens the security boundary.

Management software should reconcile existing trust state before creation, attach an owner and expiration to temporary trusts, and stop after deterministic quota failure. Alert on unusual growth per delegated principal.

Difference from the total creation quota

ERROR_ALL_USER_TRUST_QUOTA_EXCEEDED indicates that the aggregate delegated trust creation allowance is exhausted. Error 1932 can affect one user while another properly authorized delegated workflow still has capacity.

Example

A CI account creates disposable cross-domain trusts for integration tests but its cleanup job has been failing. New creation returns 1932. Removing verified orphaned test trusts and fixing reconciliation restores the account without broadening its rights.
