MESSAGE : ADM13001E  Plug-in "IBMOSauthclient" received error code "-2" from 
          the DB2 security plug-in API "db2secGetDefaultLoginContext" with the 
          error message " ".

Determines the user associated with the default login context, in other words, determines the DB2 authid of the user invoking a DB2 command without explicitly specifying a user ID

The db2secGetDefaultLoginContext API returns the user of the default login context.  In the situation , where a DB2 command is executed , but a user ID is not stated.

Notes

 1) The error occurs because either an authid or user ID (or both) are not returned .

2) These errors occur sporadically – and are considered severe by DB2.

3) This is an OS authentication issue – where some third party  is attempting to logon.

4) Typically, the issue by  adding the user to /etc/passwd  or some other list .

5) Investigate all scans occurring on the server , and map occurrence of  errors with scan

6) If Quest is installed , check  logs  for critical errors
