authentication to them. So you need to create the webdav and zotero
users and add the passwords to an htpasswd file. Even though you could
use a single user, since you will be configuring several clients with
your credentials I encourage you to create the zotero user as well. This
way you can always change the password for zotero without affecting any
other application using webdav.</p><div class=highlight><div class=chroma><table class=lntable><tr><td class=lntd><pre tabindex=0 class=chroma><code><span class=lnt>1
