Hi
> if you have no books. What websites do you recommend to learn openldap? > For some easy to follow tutorials you could go to golinuxcloud.com. Unfortunately there is no search on that page, so best to search google like with those searchterms: openldap site:golinuxcloud.com This will bring up several step-by-step tutorials. It might help to have a graphical utility to access your openldap installation. If you want a locally installed tool I suggest Apache Directory Studio: https://directory.apache.org/studio/ Or if you prefer something webbased you might want to look into phpLDAPadmin https://github.com/leenooks/phpLDAPadmin Symas has a good KnowledgeBase with short blocks of information grouped by topic mostly around installtion of OpenLDAP. Most of it is relevant for all versions of OpenLDAP, not just the one offered by Symas https://kb.symas.com/en_US/installation To install OpenLDAP yourself (depending on your OS) you might prefer pre-compiled RPM or DEB packages which you can find from the OpenLDAP Toolbox project which offers other ressources (Nagios Checks, SelfServicePassword WebUI, etc.) as well: https://ltb-project.org/ If you prefer containers then this might be a good starting point: https://hub.docker.com/r/bitnami/openldap The commandline tool ldapsearch is quite useful but especially the filters are a bit tricky to learn at first. A good explanation can be found here: https://tylersguides.com/guides/ldap-search-filters/ If you want to administer your OpenLDAP installation on the commandline then there are a couple of different options. But this gives a quick overview of some of the more often used ones: https://serverfault.com/questions/577356/ldap-backup-with-slapcat-vs-ldapsearch To dive deeper into the commandline tools you probably won't get around reading some man pages. But with the links above you should be occupied for a while. Best, Cyril
