# Nextcloud LLDAP example config
|
|
|
|
## lldap users & groups
|
|
|
|
This example is using following users & groups in lldap :
|
|
|
|
* A technical user (ex: `ro_admin`), member of `lldap_strict_readonly` or `lldap_password_manager`
|
|
* A catch-all group called `nextcloud_users`.
|
|
* Members of `nextcloud_users` group will be authorized to log in Nextcloud.
|
|
* Some "application" groups, let's say `friends` and `family`: users in Nextcloud will be able to share files and view people in dynamic lists only to members of their own group(s).
|
|
* Users in `family` and `friends` should also be users in `nextcloud_users` group!
|
|
|
|
If you plan on following this tutorial line-by-line, you will now have the following:
|
|
* 6 groups:
|
|
1. `nextcloud_users`
|
|
2. `family`
|
|
3. `friends`
|
|
4. `lldap_strict_readonly`
|
|
5. `lldap_password_manager`
|
|
6. `ldap_admin`
|
|
* 1 admin user in any of the following groups:
|
|
1. `lldap_password_manager`
|
|
2. `lldap_strict_readonly`
|
|
* (Atleast) 1 user in the `nextcloud_users` group
|
|
* (Optional) Any number of users in the `friends` or `family` group.
|
|
|
|
## Nextcloud config : the cli way
|
|
|
|
TL;DR let's script it. The "user_ldap" application is shipped with default Nextcloud installation (at least using Docker official stable images), you just have to install & enable it :
|
|
|
|
```sh
|
|
occ app:install user_ldap
|
|
occ app:enable user_ldap
|
|
occ ldap:create-empty-config
|
|
|
|
# EDIT: domain
|
|
occ ldap:set-config s01 ldapHost "ldap://lldap.example.net."
|
|
occ ldap:set-config s01 ldapPort 3890
|
|
# EDIT: admin user
|
|
occ ldap:set-config s01 ldapAgentName "uid=ro_admin,ou=people,dc=example,dc=com"
|
|
# EDIT: password
|
|
occ ldap:set-config s01 ldapAgentPassword "password"
|
|
# EDIT: Base DN
|
|
occ ldap:set-config s01 ldapBase "dc=example,dc=com"
|
|
occ ldap:set-config s01 ldapBaseUsers "dc=example,dc=com"
|
|
occ ldap:set-config s01 ldapBaseGroups "dc=example,dc=com"
|
|
occ ldap:set-config s01 ldapConfigurationActive 1
|
|
occ ldap:set-config s01 ldapLoginFilter "(&(objectclass=person)(uid=%uid))"
|
|
# EDIT: nextcloud_users group, contains the users who can login to Nextcloud
|
|
occ ldap:set-config s01 ldapUserFilter "(&(objectclass=person)(memberOf=cn=nextcloud_users,ou=groups,dc=example,dc=com))"
|
|
occ ldap:set-config s01 ldapUserFilterMode 0
|
|
occ ldap:set-config s01 ldapUserFilterObjectclass person
|
|
occ ldap:set-config s01 turnOnPasswordChange 0
|
|
occ ldap:set-config s01 ldapCacheTTL 600
|
|
occ ldap:set-config s01 ldapExperiencedAdmin 0
|
|
occ ldap:set-config s01 ldapGidNumber gidNumber
|
|
# EDIT: list of application groups
|
|
occ ldap:set-config s01 ldapGroupFilter "(&(objectclass=groupOfUniqueNames)(|(cn=friends)(cn=family)))"
|
|
# EDIT: list of application groups
|
|
occ ldap:set-config s01 ldapGroupFilterGroups "friends;family"
|
|
occ ldap:set-config s01 ldapGroupFilterMode 0
|
|
occ ldap:set-config s01 ldapGroupDisplayName cn
|
|
occ ldap:set-config s01 ldapGroupFilterObjectclass groupOfUniqueNames
|
|
occ ldap:set-config s01 ldapGroupMemberAssocAttr uniqueMember
|
|
occ ldap:set-config s01 ldapEmailAttribute "mail"
|
|
occ ldap:set-config s01 ldapLoginFilterEmail 0
|
|
occ ldap:set-config s01 ldapLoginFilterUsername 1
|
|
occ ldap:set-config s01 ldapMatchingRuleInChainState unknown
|
|
occ ldap:set-config s01 ldapNestedGroups 0
|
|
occ ldap:set-config s01 ldapPagingSize 500
|
|
occ ldap:set-config s01 ldapTLS 0
|
|
occ ldap:set-config s01 ldapUserAvatarRule default
|
|
occ ldap:set-config s01 ldapUserDisplayName displayname
|
|
occ ldap:set-config s01 ldapUserFilterMode 1
|
|
occ ldap:set-config s01 ldapUuidGroupAttribute auto
|
|
occ ldap:set-config s01 ldapUuidUserAttribute auto
|
|
```
|
|
With a bit of of luck, you should be able to log in your nextcloud instance with LLDAP accounts in the `nextcloud_users` group.
|
|
|
|
## Nextcloud config : the GUI way
|
|
|
|
1. enable LDAP application (installed but not enabled by default)
|
|
2. setup your ldap server in Settings > Administration > LDAP / AD integration
|
|
3. setup Group limitations
|
|
|
|
### LDAP server config
|
|
|
|
Fill the LLDAP domain and port, DN + password of your technical account and base DN (as usual : change `example.com` by your own domain) :
|
|
|
|
|
|
|
|
### Users tab
|
|
|
|
Select `person` as object class and then choose `Edit LDAP Query` : the `only from these groups` option is not functional.
|
|
We want only users from the `nextcloud_users` group to be allowed to log in Nextcloud :
|
|
```
|
|
(&(objectclass=person)(memberOf=cn=nextcloud_users,ou=groups,dc=example,dc=com))
|
|
```
|
|
|
|
|
|
|
|
You can check with `Verify settings and count users` that your filter is working properly (here your accounts `admin` and `ro_admin` will not be counted as users).
|
|
|
|
### Login attributes
|
|
Select `Edit LDAP Query` and enter :
|
|
```
|
|
(&(objectclass=person)(uid=%uid))
|
|
```
|
|
|
|
|
|
|
|
Enter a valid username in lldap and check if your filter is working.
|
|
|
|
### Groups
|
|
|
|
You can use the menus for this part : select `groupOfUniqueNames` in the first menu and check every group you want members to be allowed to view their group member / share files with.
|
|
|
|
|
|
|
|
## Sharing restrictions
|
|
|
|
Go to Settings > Administration > Sharing and check following boxes :
|
|
|
|
* "Allow username autocompletion to users within the same groups"
|
|
|
|
