Configuring EZproxy to gain information from multiple sources

From WCN

It might be necessary to use more than one source to construct a usable userObject. It is possible to configure the EZproxy "user.txt" file to account for such scenarios. This example also requires the create of a secondary file called "iii.txt" which will be called to perform specific III API information harvesting.

This combination mainly works with III, LDAP, and SIP, as those are the most robust sources of data.

So it is possible to do field swapping as necessary to make sure that the userObject that is returned has the "UID" set to how the user is known in both the local ILS system and in the NRE database (these data must match).

 ::LDAP
 BindUser CN=ezproxy,CN=users,DC=yourlib,DC=org
 BindPassword verysecret
 URL ldap://ldapserv.yourlib.org/CN=users,DC=yourlib,DC=org?sAMAccountName?sub?(objectClass=person)

 IfUnauthenticated; Stop

 If auth:barcode ne "" {
    # preserve provided login username
    Set saveuser = login:user

    # and switch to barcode from LDAP
    Set login:user = auth:barcode

   # Make a call to the external "iii.txt" file
    If UserFile("iii.txt") {
       # Logic to perform if III authenticated was successful as well
   }
  
 # switch back to provided username
 Set login:user = saveuser
 }
 /LDAP

Create a file called "iii.txt" and enter the contents below

 ::III
   Password None
   III iii.yourlib.org
   IfUnauthenticated; Stop

   Set session:uid = login:user
   Set ParseName(auth:pn, "S,FM,X", "session")
 /III
