419 =head1 LDAP Configuration
421 This module is specific to LDAP authentification. It requires Net::LDAP package and one or more
422 working LDAP servers.
424 * Modify ldapserver element in KOHA_CONF
425 * Establish field mapping in <mapping> element.
427 For example, if your user records are stored according to the inetOrgPerson schema, RFC#2798,
428 the username would match the "uid" field, and the password should match the "userpassword" field.
430 Make sure that ALL required fields are populated by your LDAP database (and mapped in KOHA_CONF).
431 What are the required fields? Well, in mysql you can check the database table "borrowers" like this:

547 The <mapping> subelements establish the relationship between mysql fields and LDAP attributes. The element name

549 between the element tags is taken as the default value. In this example, the default categorycode is "PT" (for
554 Once a user has been accepted by the LDAP server, there are several possibilities for how Koha will behave, depending on
555 your configuration and the presence of a matching Koha user in your local DB:
558 OPTION UPDATE REPLICATE EXISTS? RESULT
559 A1 1 1 1 OK : We're updating them anyway.
560 A2 1 1 0 OK : We're adding them anyway.
561 B1 1 0 1 OK : We update them.
562 B2 1 0 0 FAIL: We cannot add new user.
563 C1 0 1 1 OK : We do nothing. (maybe should update password?)
564 C2 0 1 0 OK : We add the new user.
565 D1 0 0 1 OK : We do nothing. (maybe should update password?)
566 D2 0 0 0 FAIL: We cannot add new user.
568 Note: failure here just means that Koha will fallback to checking the local DB. That is, a given user could login with
569 their LDAP password OR their local one. If this is a problem, then you should enable update and supply a mapping for
570 password. Then the local value will be updated at successful LDAP login and the passwords will be synced.
572 If you choose NOT to update local users, the borrowers table will not be affected at all.
573 Note that this means that patron passwords may appear to change if LDAP is ever disabled, because
574 the local table never contained the LDAP values.
578 Binds as the user instead of retrieving their record. Recommended if update disabled.
580 =head2 principal_name
582 Provides an optional sprintf-style format for manipulating the userid before the bind.
583 Even though the userPrincipalName is one intended target, any uniquely identifying
584 attribute that the server allows to be used for binding could be used.
586 Currently, principal_name only operates when auth_by_bind is enabled.
588 =head2 update_password
590 If this tag is left out or set to a true value, then the user's LDAP password
591 will be stored (hashed) in the local Koha database. If you don't want this
592 to happen, then set the value of this to '0'. Note that if passwords are not
593 stored locally, and the connection to the LDAP system fails, then the users
594 will not be able to log in at all.
596 =head2 Active Directory
598 The auth_by_bind and principal_name settings are recommended for Active Directory.
600 Under default Active Directory rules, we cannot determine the distinguishedName attribute from the Koha userid as reliably as
601 we would typically under openldap. Instead of:
603 distinguishedName: CN=barnes.7,DC=my_company,DC=com
607 distinguishedName: CN=Barnes\, Jim,OU=Test Accounts,OU=User Accounts,DC=my_company,DC=com
609 Matching that would require us to know more info about the account (firstname, surname) and to include punctuation and whitespace
610 in Koha userids. But the userPrincipalName should be consistent, something like:
612 userPrincipalName: barnes.7@my_company.com
614 Therefore it is often easier to bind to Active Directory with userPrincipalName, effectively the
615 canonical email address for that user, or what it would be if email were enabled for them. If Koha userid values
616 will match the username portion of the userPrincipalName, and the domain suffix is the same for all users, then use principal_name
618 <principal_name>%s@core.my_company.com</principal_name>
620 The user of the previous example, barnes.7, would then attempt to bind as:
621 barnes.7@core.my_company.com
