Hi all,<\/p>\n

Today I have implemented Lost Password Management using Oracle Access Manager 10.1.4.3.\u00a0 The infrastructure I have is OAM 10.1.4.3, Sun DS 5.2 as User store and Policy Store.<\/p>\n

There is a web application deployed in OHS 11g protected with Form based authentication.\u00a0 When we install OHS 11g webgate, a folder \/oamsso gets created under WebGate\/oblix location. This folder has login.html with Forgot Password button given. If you dont have such login file, then you can add the below code in your custom login file.<\/p>\n

<script content=”text\/javascript” language=”JavaScript” ><\/p>\n

function lostPassword()
\n{
\nvar elements = document.forms[0].elements;
\nname = “”;
\nfor (i=0; i<elements.length; i++)
\n{
\nname = “”+ elements[i].name;
\nif (name == “userid”)
\n{
\nif (isEmpty(document.forms[0].elements[i].value) == true)
\n{
\nalert(“Please enter a valid User Name”);
\nreturn;
\n}
\nvar newFormInput = document.createElement(‘input’);
\nnewFormInput.setAttribute(“name”,”login”);
\nnewFormInput.setAttribute(“type”,”hidden”);
\nnewFormInput.setAttribute(“value”,document.forms[0].elements[i].value);
\ndocument.loginForm.appendChild(newFormInput);
\nbreak;
\n}
\n}<\/p>\n

\/\/ REPLACE host:port with host & port of Webserver where WEBPASS is installed<\/p>\n

document.forms[0].action = “http:\/\/host:port\/identity\/oblix\/apps\/lost_pwd_mgmt\/bin\/lost_pwd_mgmt.cgi?backUrl=” + document.URL;
\n}
\n<input type=”submit” onclick=”lostPassword()” name=”button” value=”Lost Password”><\/p>\n

The basic needs to achieve Lost Password management functionality are some custom challenge phrase and response attributes with auxiliary object class.<\/p>\n

Use the below lines and add it to a LDIF file.<\/p>\n

# adding attributes
\ndn: cn=schema
\nchangetype: modify
\nadd: attributetypes
\nattributetypes: ( 1.3.6.1.4.1.9999.1.1094.206 NAME ‘Challenge Phrase1’ SYNTAX
\n1.3.6.1.4.1.1466.115.121.1.15 )
\ndn: cn=schema
\nchangetype: modify
\nadd: attributetypes
\nattributetypes: ( 1.3.6.1.4.1.9999.1.1094.207 NAME ‘Challenge Response1’ SYNTAX
\n1.3.6.1.4.1.1466.115.121.1.15 )
\n#adding aux object class
\ndn: cn=schema
\nchangetype: modify
\nadd: objectclasses
\nobjectclasses: ( 1.3.6.1.4.1.9999.1.1094.208 NAME ‘oblixAuxPerson4LPM’ DESC ‘User defined objectclass’ SUP top AUXILIARY MAY ( ChallengePhrase1 $ ChallengeResponse1 ) )<\/p>\n

Here, we are adding two attributes\u00a0 Challenge Phrase1 and Challenge Response1 to the LDAP schema along with Auxiliary Object class which uses two two attributes as optional.<\/p>\n

These attributes are used when a user is created either by administrator using Create User Identity <\/strong>or through User Self Registration (<\/strong>using Identity XML)<\/strong>.<\/p>\n

You can use the below command to add those attributes and\u00a0 object class to schema.<\/p>\n

D:\\Sun\\MPS\\shared\\bin>ldapmodify.exe -h kbmahendra.india.hcleai.com -p 30127 -D
\n“cn=Directory Manager” -w admin123 -f D:\\Sun\\LPM.ldif
\nmodifying entry cn=schema<\/p>\n

Upon executing the ldapmodify command, you should see a success message “modifying entry cn=schema”.<\/strong><\/p>\n

Restart the OC4J_SECURITY service to reflect the oblixAuxPerson4LPM <\/strong>objectclass to OAM schema.<\/p>\n

Now, you should add the object class oblixAuxPerson4LPM<\/strong> in the OAM object classes.<\/p>\n

For this, goto the Identity System Console ->\u00a0 Common Configuration -> Object Classes.<\/p>\n

Click Add and select\u00a0 oblixAuxPerson4LPM<\/strong> from dropdown. Select Object Class Type as Person. Click Modify Attributes, configure the attribute ChallengePhrase1 <\/strong>by selecting Challenge <\/strong>and DN Prefix <\/strong>as Semantic Type<\/strong>. Let the Display Type <\/strong>be Single Line Text <\/strong>and Attribute Values <\/strong>be Single<\/strong>. Similarly configure the object class ChallengeResponse1<\/strong> by selecting Response <\/strong>as Semantic Type.<\/strong><\/p>\n

Save these configurations and Click Done.<\/p>\n

Goto the Authentication scheme. Here, I am using Form Based Login.<\/p>\n

Goto the Validation Plugin and add the text and it should appear as shown below.<\/p>\n

obCredentialPassword=”password”,obReadPasswdMode=”LDAP”, obWritePasswdMode=”LDAP”<\/font><\/strong><\/p>\n

Please be careful with quotes (use ” and not \u201d).<\/p>\n

With this, the configuration part is completed. Now lets test the lost password functionality.<\/p>\n

Access the test URL protected by OAM and it should throw the login page as shown below.<\/p>\n

Enter the userid and click Lost Password.<\/p>\n

<\/a><\/p>\n

You will be prompted with Challenge Phrase that is already registered by the user. Answer the challenge phrase and click Submit<\/strong>.<\/p>\n

<\/a><\/p>\n

Now, you will be prompted to enter the new Password <\/strong>and click Save<\/strong>.<\/p>\n

<\/a><\/p>\n

It will display a message saying the password has been changed and click Back<\/strong>.<\/p>\n

<\/a><\/p>\n

Now, you will be prompted with login page again. Enter the credentials with new password and you will be shown the requested resource.<\/p>\n
