Error message when you use the "ypcat" command to query a group map on a Windows Server 2003 R2-based computer that has Identity Management for UNIX installed: "yp error"

On a Windows Server 2003 R2-based computer that has Identity Management for UNIX installed, you use the ypcat command to query a group map. However, you receive the following error message if the size of a group in the group map is exactly 1,024 bytes:When this problem occurs, users may be unable to access files and directories as expected. Additionally, applications that depend on the secondary group membership of users for authentication may fail.

This problem occurs because the group map cache cannot be built when the size of a group in the group map is 1,024 bytes.
