This is a string in the | | form of ldap://<hostname or IP>:<port>/. ldaps:// or ldapi:// can also | | be used. The port number is optional. | | | | Note: It is usually a good idea to use an IP address because it reduces | | risks of failure in the event name service problems. | | | | LDAP server Uniform Resource Identifier: | | | | ldap://dlp.srv.world/_________________________________________________ | | | | <Ok> | | | +---------------------------------------------------------------------------+ (2) specify suffix +---------------------| Configuring ldap-auth-config |----------------------+ | Please enter the distinguished name of the LDAP search base. Many sites | | use the components of their domain names for this purpose. For example, | | the domain "example.net" would use "dc=example,dc=net" as the | | distinguished name of the search base. | | | | Distinguished name of the search base: | | | | dc=srv,dc=world_______________________________________________________ | | | | <Ok> | | | +---------------------------------------------------------------------------+ (3) specify LDAP version +---------------------| Configuring ldap-auth-config |---------------------+ | Please enter which version of the LDAP protocol should be used by | | ldapns. It is usually a good idea to set this to the highest available | | version. | | | | LDAP version to use: | | | | 3 | | 2 | | | | | | <Ok> | | | +--------------------------------------------------------------------------+ (4) select the one you like. ( this example selects 'Yes' ) +---------------------| Configuring ldap-auth-config |----------------------+ | | | This option will allow you to make password utilities that use pam to | | behave like you would be changing local passwords. | | | | The password will be stored in a separate file which will be made | | readable to root only. | | | | If you are using NFS mounted /etc or any other custom setup, you should | | disable this. | | | | Make local root Database admin: | | | | <Yes> <No> | | | +---------------------------------------------------------------------------+ (5) select the one you like. ( this example selects 'No' )

(7) specify password for LDAP admin account +---------------------| Configuring ldap-auth-config |----------------------+ | Please enter the password to use when ldap-auth-config tries to login to | | the LDAP directory using the LDAP account for root. | | | | The password will be stored in a separate file /etc/ldap.secret which | | will be made readable to root only. | | | | Entering an empty password will re-use the old password. | | | | LDAP root account password: | | | | _________________________________________________________________________ | | | | <Ok> | | | +---------------------------------------------------------------------------+
