I don’t know why, but I can’t add LDAP users in a group if this user never connect to Seafile.
It is OK to users I create manualy, but for users in my LDAP, it is only possible if they are list in LDAP (imported). That mean that all LDAP users that never connect to Seafile can’t be add to a Seafile Group.
Is it normal? How can I force it?
First I have to say I don’t using LDAP. But did you try to upgrade server to the latests? What I remember there were some changes about user properties so may you will be able. Are you using CE or PRO?
I think this is normal behavior. A user has to be imported into the seafile database before the account can be used for sharing. This happens with the user’s first login to seafile. I also find this to be annoying. Here at university, a faculty member who wants to share files with his/her students, has to wait until all students have logged into seafile before s/he can add them to his group.
