Hello, 
I'm trying to use the "func=LL.login" to switch from one account to another but it always shows me this error: 
    
        
            
    
knowing that I'm using this Url: http://<host_name>/otcs/llisapi.dll?func=LL.login&username=<username>&password=<password>&nexturl=%2Fotcs%2Fcs%2Eexe%2Fapp 
I've tried to add "&" so the url became like this: http://<host_name>/otcs/llisapi.dll?func=LL.login&username=<username>&password=<password>&nexturl=%2Fotcs%2Fcs%2Eexe%2Fapp but I'm always getting this error:
    
        
            
    
Am I making any errors ?
