Using the Search Attribute Field in Authentication Maps
The purpose of the Search Attribute prompt on the authentication maps page is to map a value that is used for the User ID on the login page. For example, if you want users to log in with their mailID, then mail attribute should be given in the prompt.
Example
Consider an entry corresponding to the user adamclark in the LDAP directory.
dn: uid=adamclark, dc=peoplesoft, dc=com
cn: adamclark
uid: adamclark123
description: peoplesoft user
mail: adamclark@example.com
telephone: 12345678
objectclass: person
password: PASSWORD
If the user is to log in with adamclark/PASSWORD, then the Search Attribute prompt value should be cn. If the user wants to log in with adamclark@example.com/PASSWORD, then the Search Attribute prompt value should be mail.
