    I need a command line tool for Linux that searches an LDAP directory with a specific filter and, for each entry found, modifies two values that are part of a multi-value attribute. My LDAP directory entries have an attribute, radiusReplyItem, with multiple values. I need to modify all entries matching the filter and replace some of these values having a specific pattern with different ones, the other values must not be changed. I'm expecting a script that, provided two search values, search_value1 and search_value2, connects to an LDAP server and modifies the matching entries in the LDAP directory with replace_value1 and replace_value2, respectively. For example, I want the script to replace the values for all entries matching the filter '(&(radiusReplyItem=X-OldPlan-Out+...

    At a client we found the following architecture: 2 AD Controller with Windows Server 2016. One at the moment not working and the other store the AD User Files and Directory (Like Desktop and Documents) so that instead of having it store locally when access they work on the server ones. We need help to achieve this two point in the most "invisible" way to the enduser possible: - We added a third AD Controller which we would like to become the only one. - We would like that user data return to be stored locally instead of being stored on the server. I will attach a little diagram explaining the current status and what we would like to have.

    Hello, The project is about building a decentralized P2P network (platform) based on the IPFS or libp2p network framework. The project has 7 main phases: 1) Build a P2P network, where each node/peer participating in this network must be capable of discovering, routing, messaging, file sharing, and pinging other nodes/peers. This can be done through the IPFS or LİBP2P. This step is very easy you just need to install one of the above-mentioned protocols and then deploy it as a private (isolated) network via "Swarm / DHT". 2) Setup a VPN based on hyperspace to enable Master and Worker nodes be accessible in RAY (if you can manage it through libp2p then this task can be skipped). 3) Resource management: each node/peer must be able to manage its resources (i.e. RAM, CPU, and storage)....
