Symptoms

Using ODPNET inside ASPNET application with enabled connection pooling
and configured NTS or KERBEROS opening and closing a end users
connection (MYCOMPUTER\TESTUSER) followed by
 
  OracleConnection.ClearAllPools()
 
will cause subsequent conections to be executed as hosted web service
users - like
 
  NT AUTHORITY\NETWORK SERVICE
    
and NOT as expected as end user
  
  MYCOMPUTER\TESTUSER
  
as in the initial connection.
