ChangePassword page for FBA(Form based Authentication) for SharePoint 2007

One of the nice features of SharePoint is its pluggable authentication. Its actually a ASP.NET 2.0 feature. Since SharePoint 2007 is an ASP.NET application, SharePoint inherits it for free.

SharePoint provides an out-of-the-box login.aspx page , located in 12 hives /layouts folder, which is automatically enabled when you turn on FBA on any of the Zone. There are plenty of postings on the web on how to get your forms authentication working in WSS and MOSS

What I didn't find is change password . Once you enable the form authentication, how a user can change the password? There is a ASP.NET control but nothing out-of-the-box in SharePoint, to support this

So I decided to write a custom ASPX page to handle changepassword and provision it via "Feature" . It is very simple

Here is what the final output look like. You can download the entire sample from here.
Change Password Menu Item in Welcome menu (PersonalActions)

Change Password aspx page





Here is what I did
1) Created a simple aspx page and inherited "application.master" master page. Application.Master is located in /layouts folder . You can use any of the master pages from the /layouts folder or create a custom one.
2) Drop asp:changepassword control in the content area
<asp:changepassword id="ChangePassword1" newpasswordregularexpressionerrormessage="Error: Your password must be at least 7 characters long, and contain at least one number and one special character." newpasswordregularexpression=""></asp:changepassword>
3) Copy this page to 12 hives /layouts folder
4) Create a <CustomAction> Feature set the feature URL to /_layouts/changepassword.aspx page
<customaction id="ChangePasswordMenuId" title="Change Password" description="Change Password control" sequence="2000" location="Microsoft.SharePoint.StandardMenu" groupid="PersonalActions" > <UrlAction Url="~site/_layouts/changepassword.aspx"/>

5) Install the feature using STSADM.exe


And there you go!! You have the changepassword page with very little effort.

May be Microsoft can include this as a out of the box feature in the next version of SharePoint :)

after download, rename the file to changepassword.aspx and copy it in 12/_layouts/folder

I get an error when I try this code:

c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\LAYOUTS\changepassword.aspx(5): error CS0117: 'ASP._layouts_changepassword_aspx' does not contain a definition for 'OnCancelBtn' at System.Web.Compilation.AssemblyBuilder.Compile()

This is exactly what I need but I am having trouble with creating the feature. Can anyone assist ?

lbr said...

Hi, thanks for article.
I faced some issues applying your control.

Creation -

mkdir \12\TEMPLATE\FEATURES\ChangePasswordFBA
two files go there
feature.xml and operations.xml


feature.xml -

__?xml version="1.0" encoding="utf-8"?__
__Feature Id="00BAAA71-7AAD-4AA6-9BA8-C047AC750105"
Title="Change Password"
Description="Change Password"
Version="1.0.0.0"
Scope="Web"
xmlns="http://schemas.microsoft.com/sharepoint/">
__ElementManifests>
__ElementManifest Location="operations.xml" />
__/ElementManifests>
__/Feature__



operations.xml -


__?xml version="1.0" encoding="utf-8"?>
__Elements
xmlns="http://schemas.microsoft.com/sharepoint/">
__CustomAction
Id="ChangePasswordMenuId"
Title="Change Password"
Description="Change Password control"
Sequence="2000"
Location="Microsoft.SharePoint.StandardMenu"
GroupId="PersonalActions">
__UrlAction Url="_layouts/changepassword.aspx"/>
__/CustomAction>
__/Elements>

replace __ with < (blogger doesn't allow those tags)


Install -

stsadm -o installfeature -filename ChangePasswordFBA\Feature.xml

stsadm -o activatefeature -filename ChangePasswordFBA\Feature.xml -url http://your_site_here


Also changepassword.aspx should be corrected -

remove -OnCancelButtonClick="OnCancelBtn" OnContinueButtonClick="OnCancelBtn"

otherwise SharePoint returns error.

Also, there is nice articel here -

Hi ,
I could sucessfully implement the change password option to personal action groups.
But only a user with "full control" is able to acess the change password option.
Others are getting access denied error.
Plz help me.

Thanks
Sherin
