I’m trying to configure an admin account where only 1 client can access at the same time.

If two users each access the same control page at the same time can cause problems

Advanced Web Server  
Toolkit describe a concept called realm locking but i’m not sure if i’m implementing it correctly… actually i’m sure that as i’m doing it’s not working ;).

Account creation:

```auto
NAsetSysAccess (NASYSACC_ADD, "admin", "admin", NASYSACC_LEVEL_HTTP_R1 | NASYSACC_LEVEL_RW, NULL);

```

Define security for realm HTTP\_R1

```auto

void RpHSInitSecurityTable(void *serverdata)
{
	NAHttpSetRealmSecurity (0, "NA-HTTP AWS Realm 1", NA_HTTP_SECURITY_SINGLE_ACCESS, NA_HTTP_SECURITY_BASIC_AUTHENTICATION);
}

```
