    OUT BOOL* pfGlobal              // set true if global creds found
    )

// Loads the credentials for the given entry into memory.  This routine 
// determines whether per-user or per-connection credentials exist or 
// both. 
// 
// The logic is a little complicated because RasGetCredentials had to 
// support legacy usage of the API.
//
// Here's how it works.  If only one set of credentials is stored for a 
// connection, then RasGetCredentials will return that set regardless of 
// whether the RASCM_DefalutCreds flag is set.  If two sets of credentials
// are saved, then RasGetCredentials will return the per-user credentials
// if the RASCM_DefaultCreds bit is set, and the per-connection credentials
// otherwise.
//
// Here is the algorithm for loading the credentials
//
// 1. Call RasGetCredentials with the RASCM_DefaultCreds bit cleared
//    1a. If nothing is returned, no credentials are saved
//    1b. If the RASCM_DefaultCreds bit is set on return, then only
//        global credentials are saved.
//
// 2. Call RasGetCredentials with the RASCM_DefaultCreds bit set
//    2a. If the RASCM_DefaultCreds bit is set on return, then 
//        both global and per-connection credentials are saved.
//    2b. Otherwise, only per-user credentials are saved.
