Hello again,

First of all, sorry in advance for my multiple posts with beginner questions, still trying to get the hang of the feature-filled API of Servoy.

I first created an unsecure login form that just checked the Username and Password in the DB, and then proceeded.  
After looking around though, it seems I should be using the security functions that come with Servoy.

I have written some code to try and perform this task:

function loginToForm(event){  
var userUID = security.getUserUID(userNameField);  
var userGroups = security.getUserGroups(userUID);  
var checkPW = security.checkPassword(userUID,passWordField);

if(checkPW){  
security.login(userNameField,userUID,userGroups);  
application.output(‘logged in’);  
}  
else {  
application.output(‘failed login’);  
}  
}

userNameField and passWordField are tied to text areas on the form where the user inputs their information.

I am getting an error on the security.login line, saying I cannot provide String,String,JSDataSet, and instead to provide String,Object,Array.  
As you can tell I am using the supported methods that come with the Security property. Why won’t the provided methods fit together? Shouldn’t security.getUserUID return the UID in a manner that would fit the security.login method?

Thanks in advance for any assistance!  
Chris

Hi Chris,

actually the ‘getUserGroups’ function is returning a dataset.  
from that dataset you need to get the correct column (thought this is column 2) as an array:

```auto
/** @type {Array<String>} */
var groupArray = userGroups.getColumnAsArray(2);

```

Then use the groupArray to pass to the login function.

Hope this helps

Thanks for the assistance!  
I had already tried the getColumnAsArray(2), tho what fixed it is adding the /\*\* @type {Array} \*/  
I was under the impression that doc comments weren’t programatically relevant, but it seems I am wrong.

**EDIT: I noticed when I launch the smart client it’s automatically logging me in to some “dummy-login”. How am I supposed to test out my own login solution if the system keeps auto logging me in dummy-login?**

_Why would the security.login() return false?_  
_I have traced each value I am passing into the function, which has the correct username, UUID, and groups, but it just returns false no matter what._  
_What could be causing this?_  
_Thanks,_
