 +
 +By default it uses normal system users and their passwords (root for admin).
 +By default CUPS **@SYSTEM** group is mapped to system **lpadmin** group, so user should be added into **lpadmin** group.
 +
 +To create internal CUPS users:
 +<code bash>
 +lppaswd -g lpadmin -a username
 +</code>
 +and file **/etc/cups/passwd.md5** will be created/updated
 +
 +For more permissions look into **/etc/cups/cupsd.conf**

 +Error: "failed to set file mode"
 +Issue not related to apparmor (not enabled).
 +
 +Solution:
 +  Error is generated by cups-pdf but is relative to ghostscript rights. Ghostscript seems to need full rights in its temp work dir.
 +  Setting "GSTmp /tmp" instead of "GSTmp /var/tmp" in /etc/cups/cups-pdf.conf solves the problem for me.
