I'm trying to create a visualforce page that has a lookup field for users, and then one you find a user, I want there to be a custom button. If the user is frozen, I want the user to be unfrozen, and if the user is not frozen, I want the button to freeze the user. I know there is a isFrozen field on the UserLogin object, but from what I can tell that is just able to show whether or not users are frozen, it doesn't deal at all with the freezing/unfreezing of users. Any ideas on how this could be done? Thanks!


When I try to set the value of the freeze and unfreeze, it says that the field 'uLogin.isFrozen' is not writeable. I've added the code I have so far below:


    public with sharing class FreezeUser {

    User_Freeze__c uf;
    User usr;
    UserLogin uLogin;

    public FreezeUser(){
        uf = new User_Freeze__c();
        usr = new User();
        uLogin = new UserLogin();

    public User getUsr(){
        return usr;

    public User_Freeze__c getUf(){
        return uf;

    public UserLogin getULogin(){
        return uLogin;

    public PageReference save(){
            System.debug('++++++++++++++++++++++++++++++++++ userFreeze on BEFORE SAVE: ' + uf);
            upsert uf;
            System.debug('++++++++++++++++++++++++++++++++++ userFreeze on AFTER SAVE: ' + uf);
            System.debug('++++++++++++++++++++++++++++++++++ userLogin isFrozen AFTER Save ' + uLogin.IsFrozen);
            System.debug('++++++++++++++++++++++++++++++++++ userLogin UserId: ' + uLogin);
            //System.debug('++++++++++++++++++++++++++++++++++ userLogin UserId: ' + uLogin.id);
        } catch(System.DmlException e){
            return null;

        return null;

    public PageReference freeze(){
            System.debug('+++++++++++++++++++++++++++++++++ User isFrozen BEFORE Update ' + uLogin.isFrozen);
            if(uLogin.isFrozen == false){
                uLogin.IsFrozen = true;
                update uLogin;
            System.debug('+++++++++++++++++++++++++++++++++++++ User isFrozen AFTER Update' + uLogin.isFrozen);

            return null;

        } catch(System.DMLException e){
            return null;

    public PageReference Unfreeze(){
            if(uLogin.isFrozen == true){
                uLogin.IsFrozen = false;
                update uLogin;
        } catch(System.DMLException e){
            return null;

        return null;

            <!-- Freeze Button -->

    Hey Stephen, by updating the IsFrozen field to true or false, you are essentially freezing or unfreezing the user, just as much as you can deactivate a user based on the value you set the isActive field. – sw6 - KTBFFH Jun 2 '15 at 12:53
  • It's really that easy? Wow. Ok, thanks. – Stephen Jun 2 '15 at 12:54
  • @sw6-KTBFFHChelseafc, so I tried to update the field, and it said it's not writeable. Any ideas? – Stephen Jun 2 '15 at 20:37

It looks like Bob Buzzard has blogged about a way to workaround not being able to set the field via apex, take a look at the full blog post here:

After digging through the Apex Developer’s Guide and experimenting with the execute anonymous element of the developer console it quickly became clear that I couldn’t freeze a user in Apex. Searching the SOAP API Developer’s Guide proved more productive when I came across the UserLogin object and its associated IsFrozen field. While this still mean that I couldn’t use Apex, the SOAP API is accessible via the Ajax Toolkit which I can use from a Visualforce page.

It was then short work to create The Freezer - a Visualforce page to output all usernames present in the system and allow them to be frozen/defrosted at the click of a button. The page is shown below:

    Thanks. I saw this before, and was hoping there was another way, but it looks like from the support this post got, that this is the way to go. – Stephen Jun 9 '15 at 12:29
  • I have the button and everything seems to work as an administrator, but when I try to use it as another user it doesn't work, and pops up the "Insufficient Privileges" Error. Any suggestions? – Stephen Jun 24 '15 at 18:45
  • @Stephen Do they have the "Manage Users" privilege? – Jenny B Jun 24 '15 at 18:48
  • We have them as a Delegated Administrator right now. – Stephen Jun 24 '15 at 19:25
  • @Stephen it doesn't look like Delegated Administrators can do that at this point, but there is an idea here success.salesforce.com/ideaView?id=08730000000kuEZAAY – Jenny B Jun 24 '15 at 19:42

No trickery involving API callouts is necessary - UserLogin.IsFrozen is absolutely "updateable" from Apex, however, check these things:

  • Your API version supports it. I used Apex API v33.0. Winter 14, when this feature was released may not have
  • You have access edit to the object, record and field in question (I did this as SysAd)
  • If you're building a Visualforce controller, you may need to make the controller "without sharing" or have it call a method in a class "without sharing" should the intended users not have the permission to freeze/thaw users directly
  • The relationship from UserLogin to User doesn't seem to be traversable with SOQL
  • You're not freezing your own (current) user as the test

Here is quick code demo to run via anonymous apex (yes, I ran this, then copy/pasted it, only anonymizing the username):

String uname = 'testuser@sfdcorg.com';
User u = [Select Id, Name FROM User WHERE Username = :uname LIMIT 1];
UserLogin ul = [SELECT Id, UserId, IsFrozen from UserLogin WHERE UserId = :u.Id LIMIT 1];

ul.IsFrozen = true;
update ul;

// Just to be sure I'm reading the stored value
ul = [SELECT Id, UserId, IsFrozen from UserLogin WHERE UserId = :u.Id LIMIT 1];

ul.IsFrozen = false;
update ul;

ul = [SELECT Id, UserId, IsFrozen from UserLogin WHERE UserId = :u.Id LIMIT 1];

results in the following log output:

the isFrozen field can be updated. I hope the code below could be of help to you:

public with sharing class FreezeUser {
    user u {get;set;}
    public userlogin ul;
    ul = [SELECT Id, UserId,IsFrozen FROM UserLogin WHERE userId =:u.Id][0]; //assuming the user id has been set from the visualforce as you described
    system.debug('ul is: '+ul);
    public PageReference freeze(){      
        if(ul.isFrozen == false){
            ul.isFrozen = true;
            update ul;
        system.debug('ul is: '+ul);
        return null;
  • That didn't seem to work. Any other ideas? – Stephen Jun 4 '15 at 17:29
  • What part of the code didn't work? What errors did you get? What was the result of the "system.debug('ul is: '+ul);" statement? – sw6 - KTBFFH Jun 4 '15 at 18:17
  • @sw6-KTBFFHChelseafc there's a bug in your code. if(ul.isFrozen = false){ should use a double equals for comparison, this is an assignment statement. The code within the scope brackets never gets executed as written. – Mark Pond Jun 4 '15 at 19:55
  • @MarkPond - thanks for catching that - missed that one when typing my answer in. Will make the edit to my answer. – sw6 - KTBFFH Jun 4 '15 at 19:59
  • @sw6-KTBFFHChelseafc when I use your code I get "unexpected token: '='" on line 4 where you set the value of userLogin ul. Not sure why I'm getting that. – Stephen Jun 5 '15 at 13:41
