apt -y install libnss-ldap libpam-ldap ldap-utils (1) specify LDAP server's URI +-----------------------| Configuring libnss-ldap |-------------------------+ | Please enter the URI of the LDAP server to use. 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 libnss-ldap |-------------------------+ | 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 (select "3" on here) +-----------------------| Configuring libnss-ldap |------------------------+ | 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) specify admin's suffix +-----------------------+ Configuring libnss-ldap +------------------------+ | Please enter the name of the LDAP administrative account. | | | | This account will be used automatically for database management, so it | | must have the appropriate administrative privileges. | | | | LDAP administrative account: | | | | cn=admin,dc=srv,dc=world________________________________________________ | | | | <Ok> | | | +--------------------------------------------------------------------------+ (5) specify password for LDAP admin account +-----------------------| Configuring libnss-ldap |-------------------------+ | 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> | | | +---------------------------------------------------------------------------+ (6) [OK] +-----------------------+ Configuring libnss-ldap +------------------------+ | | | nsswitch.conf not managed automatically | | | | For the libnss-ldap package to work, you need to modify your | | /etc/nsswitch.conf to use the "ldap" datasource. There is an example | | file at /usr/share/doc/libnss-ldap/examples/nsswitch.ldap which can be | | used as an example for your nsswitch setup, or it can be copied over | | your current setup. | | | | Also, before removing this package, it is wise to remove the "ldap" | | entries from nsswitch.conf to keep basic services functioning. | | | | <Ok> | | | +--------------------------------------------------------------------------+ (7) select the one you like. (select "Yes" on here) +------------------------+ Configuring libpam-ldap +------------------------+ | | | This option will allow password utilities that use PAM to change local | | passwords. | | | | The LDAP admin account password will be stored in a separate file which | | will be made readable to root only. | | | | If /etc is mounted by NFS, this option should be disabled. | | | | Allow LDAP admin account to behave like local root? | | | | <Yes> <No> | | | +---------------------------------------------------------------------------+ (8) select the one you like. (select "No" on here)
+---------------------| Configuring libpam-ldap |----------------------+
| |
| Choose this option if you are required to login to the database to |
| retrieve entries. |
| |
| Note: Under a normal setup, this is not needed. |
| |
| Does the LDAP database require login? |
| |
| <Yes> <No> |
| |
+----------------------------------------------------------------------+
(9) specify admin's suffix +-----------------------+ Configuring libpam-ldap +------------------------+ | Please enter the name of the LDAP administrative account. | | | | This account will be used automatically for database management, so it | | must have the appropriate administrative privileges. | | | | LDAP administrative account: | | | | cn=admin,dc=srv,dc=world________________________________________________ | | | | <Ok> | | | +--------------------------------------------------------------------------+ (10) specify password for LDAP admin account +------------------------+ Configuring libpam-ldap +------------------------+ | Please enter the password of the administrative account. | | | | The password will be stored in the file /etc/pam_ldap.secret. This will | | be made readable to root only, and will allow libpam-ldap to carry out | | automatic database management logins. | | | | If this field is left empty, the previously stored password will be | | re-used. | | | | LDAP administrative password: | | | | ********_________________________________________________________________ | | | | <Ok> | | | +---------------------------------------------------------------------------+
