Article Description

This article teaches you how to use the User Change Password (UCP) service in Cisco ACS to allow users defined in the ACS internal database to first authenticate themselves and then change their own password.

UCP through Command Line

UCP through Command Line

In this section we will see how to make use of the default script provided with ACS to enable users to change their password on ACS local database.

Let us begin with installing and configuring components that will enable UCP.

  1. Get the required files from ACS. Navigate to System Administration > Downloads > User Change Password > Python Script for Using the User Change Password Web Service (along with installation instructions), as shown in figure 7.

    2. Figure 7

    ACS will prompt you to save a file ‘pythonUCP.zip’. Save it.

  2. Next we need to install Python 2.4.

    3. For Windows we can get a windows installer for Python 2.4 from http://www.python.org/download/releases/2.4.4/.

    For Linux, we can get the source and compile from above link.

    I already had Python 2.6.5 installed on my Ubuntu box. To make script work we need 2.4.x, so I installed it as

    ~$ wget http://mirror.aarnet.edu.au/pub/ubuntu/archive/pool/main/p/python2.4/
   python2.4-minimal_2.4.6-1ubuntu3.2.9.10.1_i386.deb -O python2.4-minimal.deb
~$ wget http://mirror.aarnet.edu.au/pub/ubuntu/archive/pool/main/p/python2.4/
   python2.4_2.4.6-1ubuntu3.2.9.10.1_i386.deb -O python2.4.deb
~$ wget http://mirror.aarnet.edu.au/pub/ubuntu/archive/pool/main/p/python2.4/
   python2.4-dev_2.4.6-1ubuntu3.2.9.10.1_i386.deb -O python2.4-dev.deb
~$ sudo dpkg -i python2.4-minimal.deb python2.4.deb python2.4-dev.deb
  3. Extract the contents of pythonUCP.zip.

    4. Extract files using any unzipping utility.

    On Windows:

    Figure 8

    On Ubuntu:

    ~$ unzip pythonUCP.zip

  4. Install PyXML.

    5. On Windows, simply execute the ‘PyXML-0.8.4.win32-py2.4.exe’ file.

Service Announcements

On rare occasions it is necessary to send out a strictly service related announcement. For instance, if our service is temporarily suspended for maintenance we might send users an email. Generally, users may not opt-out of these communications, though they can deactivate their account information. However, these communications are not promotional in nature.

This site is not directed to children under the age of 13.

Marketing

Pearson may send or direct marketing communications to users, provided that

  • Pearson will not use personal information collected or processed as a K-12 school service provider for the purpose of directed or targeted advertising.
  • Such marketing is consistent with applicable law and Pearson's legal obligations.

Pearson may provide personal information to a third party service provider on a restricted basis to provide marketing solely on behalf of Pearson or an affiliate or customer for whom Pearson is a service provider. Marketing preferences may be changed at any time.

Correcting/Updating Personal Information

If a user's personally identifiable information changes (such as your postal address or email address), we provide a way to correct or update that user's personal data provided to us. This can be done on the Account page. If a user no longer desires our service and desires to delete his or her account, please contact us at customer-service@informit.com and we will process the deletion of a user's account.
