* setup command: test or create the ldap connection and hierarchy
*
2010-08-31 11:33:29 +02:00
* All commands can be run via setup-cli eg:
*
* setup/setup-cli.php [--dry-run] --setup_cmd_ldap <domain>,<config-user>,<config-pw> sub_command=set_mailbox \
* ldap_base=dc=local ldap_root_dn=cn=admin,dc=local ldap_root_pw=secret ldap_host=localhost
*
* Changing uid/gidNumber to match SID in preparation to Samba4 migration:
*
* setup/setup-cli.php [--dry-run] --setup_cmd_ldap <domain>,<config-user>,<config-pw> sub_command=sid2uidnumber \
* ldap_base=dc=local ldap_root_dn=cn=admin,dc=local ldap_root_pw=secret ldap_host=localhost
*
* - First run it with --dry-run to get ids to change / admin-cli command to change ids in EGroupware.
* - Then run admin/admin-cli.php --change-account-id and after this command again without --dry-run.
* - After that you can run the given setup/doc/chown.php command to change filesystem uid/gid in samba share.
* This is usually not needed as samba-tool clasicupgrade takes care of existing filesystem uid/gid by installing
* rfc2307 schema with uidNumber attributes.
*
* setup/setup-cli.php [--dry-run] --setup-cmd-ldap <domain>,<config-user>,<config-pw> sub_command=copy2ad \
* ldap_base=dc=local ldap_root_dn=cn=admin,dc=local ldap_root_pw=secret ldap_host=localhost \
* ads_domain=samba4.intern [ads_admin_user=Administrator] ads_admin_pw=secret ads_host=ad.samba4.intern [ads_connection=(ssl|tls)] \
* attributes=@inetOrgPerson,accountExpires=shadowExpire
*
* - copies from samba-tool clasicupgrade not copied inetOrgPerson attributes and mail attributes to AD
*
* setup/setup-cli.php [--dry-run] --setup-cmd-ldap <domain>,<config-user>,<config-pw> sub_command=copy2ad \
* ldap_base=dc=local ldap_root_dn=cn=admin,dc=local ldap_root_pw=secret ldap_host=localhost \
* ads_domain=samba4.intern [ads_admin_user=Administrator] ads_admin_pw=secret \
* ads_host=ad.samba4.intern [ads_connection=(ssl|tls)] [no_sid_check=1] \
* attributes={smtp:}proxyAddresses=mail,{smtp:}proxyAddresses=mailalias,{quota:}proxyAddresses=mailuserquota,{forward:}proxyaddresses=maildrop
*
* - copies mail-attributes from ldap to AD (example is from Mandriva mailAccount schema, need to adapt to other schema!)
* (no_sid_check=1 uses all objectClass=posixAccount, not checking for having a SID and uid not ending in $ for computer accounts)
*
* setup/setup-cli.php [--dry-run] --setup-cmd-ldap <domain>,<config-user>,<config-pw> sub_command=passwords_to_sql \
* ldap_context=ou=accounts,dc=local ldap_root_dn=cn=admin,dc=local ldap_root_pw=secret ldap_host=localhost
*
* - updating passwords for existing users in SQL from LDAP, eg. to switch off authentication to LDAP on a SQL install.
