ERROR_DS_CONSTRAINT_VIOLATION
ERROR_DS_CONSTRAINT_VIOLATION (0x0000202F) is an Active Directory Domain Services LDAP result. The LDAP modify or add request violates a directory constraint that is not represented by a more specific error.
Request the server’s extended LDAP error data and inspect the target attribute schema, object state, and directory policy. The generic constraint result often becomes actionable only when the server-supplied diagnostic explains which rule rejected the value.
What to check
- Inspect the LDAP diagnostic message for the exact attribute, policy, or object rule that failed.
- Check mandatory attributes, valid values, uniqueness requirements, and whether the object is protected by directory policy.
- Compare the request with a known-good object rather than making trial-and-error changes in production.
