![]() ![]() The LDAP directory service is based on a client-server model. It provides a mechanism used to connect to, search, and modify Internet directories. Ordinarily, if you've configured LDAP The Lightweight Directory Access Protocol (LDAP) is a directory service protocol that runs on a layer above the TCP/IP stack. You can create an additional-groups.txt file both to create new groups in PaperCut NG/MF and to populate those groups with existing PaperCut NG/MF users. Save the file as additional-groups.txt in /server/data/conf/īypass LDAP connections using a text file The format is a simple, tab-delimited list of groups and their associated users, with one group and one user per line, for example: You need to place your group definition file in the same directory. There's an example template and further information in the file called in /server/data/conf/ If it's not possible to define the required groups using your network directory, you can define them via a text file (for example, a tab-delimited file). There are some situations where it’s not possible to maintain groups within the network directory source, for example, you might not have read-access to the domain. It is similar to the 'Everyone' special group in Windows. This group is not related to any existing network group and is a 'catch all' group that represents the all users list in the PaperCut system. PaperCut NG/MF includes one built-in group called the group. On the left side, select the group(s) required then click the Add arrow. In the Actions menu, click Add/Remove groups. You need to add the required groups to the Group List.Ĭlick the Groups tab. The groups are not, however, automatically displayed in the Group List. When you import users into PaperCut NG/MF from a user directory, the groups in that directory are also imported. Add an imported group to the PaperCut NG/MF Group List To ensure administrators are not overwhelmed with all groups, PaperCut NG/MF only lists the groups that the administrator selected as relevant. In many cases only a small percentage of these groups are pertinent to PaperCut NG/MF management. Large networks can contain hundreds of groups and/or organizational units. To ensure PaperCut NG/MF is a good network application and does not overload domain controllers with group membership requests. Groups are mirror/cached for two reasons:įor fast reporting and search performance. To see the changes immediately, you just need to refresh the group membership. Therefore, changes in group membership made at the domain level might not be immediately reflected in PaperCut. PaperCut NG/MF mirrors (caches) domain network group memberships for performance reasons. To filter/restrict user behavior and access.įor use with Print Deploy to determine which users are sent which print queues. To assist with making modifications to user accounts by group. To automate the addition of new (future) user accounts. To control how quota/credit is allocated to users on a regular basis. Groups in PaperCut are used in the following ways: PaperCut NG/MF sources groups and group members from a selected directory/domain source, enabling SysAdmins to take advantage of the existing network structure. Users are recommended to upgrade to the fixed versions of PaperCut MF and NG as soon as possible, regardless of whether the server is "Available to external or internal connections," to mitigate potential risks.Ĭustomers who are unable to upgrade to a security patch are advised to lock down network access to the servers by blocking all inbound traffic from external IPs and limiting IP addresses to only those belonging to verified site servers.Available in PaperCut NG and PaperCut MF. "Potentially, the access gained through PaperCut exploitation could be used as a foothold leading to follow-on movement within the victim network, and ultimately ransomware deployment." "PaperCut has conducted analysis on all customer reports, and the earliest signature of suspicious activity on a customer server potentially linked to this vulnerability is 14th April 01:29 AEST / 13th April 15:29 UTC," it further added.Ĭybersecurity company Huntress, which found about 1,800 publicly exposed PaperCut servers, said it observed PowerShell commands being spawned from PaperCut software to install remote management and maintenance software like Atera and Syncro for persistent access and code execution on the infected hosts. Print management software provider PaperCut said that it has "Evidence to suggest that unpatched servers are being exploited in the wild," citing two vulnerability reports from cybersecurity company Trend Micro. ![]()
