using hook for client_check_cb

[David K. Sayre]

I have another interesting problem. I am authenticating users fine,  
but I would like to distinguish between authenticated and non- 
authenticated users. Basically I would like to let people log in  
without authenticating, but let the users know if they are talking to  
an authenticated user.

The initial thought is that I would append something to the end of  
the nick. So I am attempting to append a * or a _lanl.  The problem I  
am getting is that when I rename a user, I start getting error  
messages to the clients stating "Server load is temporarily too  
heavy. Please wait a while and try again".

Here is an exempt of the code I am using,

void *pam_auth(va_list args)
{
         struct Client *source_p = va_arg(args, struct Client *);
         const char *username = va_arg(args, const char *);
....
         user = source_p->name;
         user_auth = (char *)malloc(sizeof(char) * (strlen(user) + 6));

         sprintf(user_auth, "%s_lanl", user);
....
         if (retval == PAM_SUCCESS) {
                 ilog(L_INFO, "%s Authenticated\n", user);
                 change_local_nick(source_p,source_p,user_auth);
         } else {
                 ilog(L_INFO, "%s Not Authenticated\n", user);
         }

Are there any ideas out there? Should I not be sending in my source_p  
as the client and server?
