Too many security IDs have been specified.
Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_TOO_MANY_SIDS with the numeric value of 1389 and hexadecimal representation 0x56D is returned when an operation involving security identifiers (SIDs) receives more SIDs than are permitted.
Error Details
This error typically occurs in scenarios where a function or API that processes multiple SIDs encounters a limit on the number of SIDs it can handle. The specific context depends on the API being used, but generally, this error indicates an issue with the input parameters provided to the operation.
Usage Context
The ERROR_TOO_MANY_SIDS is commonly encountered in operations related to security and access control, such as setting permissions or managing user and group memberships within a file system or other security-related APIs. It can also appear when dealing with complex security configurations that involve multiple SIDs.
Developer Interpretation
When this error code is returned, it signifies that the number of SIDs specified in an operation exceeds the maximum allowed by the underlying API or function. Developers should ensure that the correct number of SIDs are provided and that they do not exceed any predefined limits set by the system.
