Could not read value for attribute

User action:
Expanding a directory in the CDS viewer, or examining a directory.

Meaning:
When expanding a directory in the CDS List Viewer, the CDS_Class attribute of all non-DCE server object entries is read to determine if the entry contains an RPC profile or an RPC group. If CDS_Class has no attribute, a pop-up message with this error is displayed.

Corrective action:
Click the OK button to dismiss the error and continue browsing. Examine the CDS object entry with the CDS control program (CDSCP), and correct the problem.
