ERROR_DS_PARAM_ERROR
ERROR_DS_PARAM_ERROR (0x0000203F) is an Active Directory Domain Services LDAP result. One or more LDAP operation parameters are invalid for the request the client sent.
What to check
- Capture the exact LDAP operation, controls, search scope, base DN, and attribute list.
- Validate each parameter against the operation type instead of changing multiple values at once.
- Reproduce the request with a minimal supported set of parameters to identify the invalid field.
