I would like to prevent users from changing their passwords. Is there a way to lock all passwords so only administrators can change them?

We have many users who we will setup in DotNetNuke who also have accounts for another system so we want those passwords to be the same.  In the other system they cannot change their password either.  I looked and didn't find a place to lock the password.

I'm running:

Thanks!

Hi Keith,

The underlying ASP.NET membership provider does not allow for permanent locking of passwords in this manner.  Your best recourse is to write a custom provider that overrides and swallows password-changing functionality (this is a moderately difficult development task).  A quicker, but dirtier solution would be to add a trigger to the relevant aspnet_* membership table that aborts any change to the password field (or alter the ascx UI itself).  This wouldn't be very upgrade friendly, however, and I am always loathe to suggest such a solution.

It is possible that there exists a third-party solution that effectuates this sort of behavior, as well.

Hope this helps!

Brandon

You could make a small change to the DNN CORE Password.ascx.vb to hide the password panel.  You find the passwordascx.vb file under [DNN Web Root]/admin/Users.  This change will be overwritten when you upgrade DNN.

Below is example code:


        Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
            If IsAdmin Then
                pnlChange.Visible = True
            Else
                pnlChange.Visible = False
            End If
        End Sub

Thank you, that did exactly what I needed.  Also, thanks for the reminding me that it will get overwritten with updates so I can put it back in after these.
