Hi!
I get the warning “The function login(String,Object,Array) is not applicable for the arguments (String,String,Array)”
in this login method in the authenticator modul:
```auto
function gm_login(vUser,vPwd) {
//check if user name exists
if(vUser){
var vUid = security.getUserUID(vUser); //get the uuid
//check if user exists
if(vUid){
//check if password exists
if(vPwd){
if(security.checkPassword(vUid,vPwd)){
var vGroups = security.getGroups().getColumnAsArray(2); //'Administrator', 'Users'
//login
var ok = security.login(vUser,vUid,vGroups);
.
.
```
If I take the sample code for security.login():
```auto
var groups = new Array()
groups[0] = 'Administrators'; //normally these groups are for example received from LDAP
var user_uid = globals.email; //also this uid might be received from external authentication method
var ok = security.login(globals.username, user_uid, groups)
if (!ok) {
plugins.dialogs.showErrorDialog('Login failure', 'Already logged in? or no user_uid/groups specified?', 'OK')
}
```
I get the same warnig!?
A little help would be nice for fixing this.

2 ways to solve this
cast it:
```auto
/**
* @type {Array}
*/
var groups = new Array();
```
or directly created it as a String array:
```auto
var groups = ['Administrators']
```
will update the sample.

Thank you Johan!
It works now without warnings:
```auto
/**
*
* @param {String} vUser
* @param {String} vPwd
*
*
* @properties={typeid:24,uuid:"C4ABD2B9-4550-4342-AF94-E636B0160193"}
*/
function gm_login(vUser,vPwd) {
//check if user name exists
if(vUser){
var vUid = security.getUserUID(vUser); //get the uuid
//check if user exists
if(vUid){
//check if password exists
if(vPwd){
if(security.checkPassword(vUid,vPwd)){
/**
* @type {Array}
*/
var vGroups = security.getGroups().getColumnAsArray(2); //'Administrators', 'Users'
//login
var ok = security.login(vUser,vUid,vGroups);
if(ok == true){
return 0;
}
else {
return null;
}
}
//password did not match
else {
return 1;
}
}
//user did not enter password
else {
return 2;
}
}
//user did not match in security
else {
return 3;
}
}
//user did not enter user name
else {
return 4;
}
}
```
