I want to prevent root users on remote machines to change the ldap users accounts details and keep it only permitted to the local server root.
Thanks
You didn't state which LDAP server, but if, as seems probable, you're using OpenLDAP, you can't stop root users from doing anything. You shouldn't have root users. The root user is for use by the server itself. Nobody else should use it. Nobody else should even know about it. You should have admin users, defined in the directory itself, and then you can specify their acces rights very extensively in the slapd configuration.

I'm hosting my file server on GCP debian 10 virtual machine and I want to create passwordless user so people could publicly download files from his home directory.
So I created new user, removed his password with passwd -d username, changed /etc/ssh/sshd_config file so it would allow this exact user to login with empty password and set chroot jail, restarted ssh service.
Unfortunately, when I'm connection via ssh into this user it still prompts me with a password.
This setup was working on the old server, configs are definitly correct and user definitely does not have password. I guess google implemented some additionl protection that dosen't allow me to do what I want.
Maybe someone had already bumbed into the same problem before?
I reached the support and they said google doesn't support passwordless ssh connections.
I want to share files and folders kept in NAS drive through IIS FTP server.
User is able to see all files including my symbolic link of folder which is on NAS drive but when user try to access he/she gets error "username or password incorrect".
How do I make NAS drive files available through my IIS FTP server.
Make sure you have assigned the iis_iusrs and iusr permission to the shared folder. check FTP authentication basic is disabled and anonymous is enabled:
add authorization allow rule for the user:
at the time of connection enter the username: testdomain/administrator and password correctly.
I have a admin website where every url requires some level of permissions. One of these urls is for deleting user's folder via SSH (different machine). Admin with required rights for this url has also access to all informations about every user (except gdpr restricted). Basically, its kind of superadmin. This admin POSTs username which is part of path used in ssh shell cmd(vulnerability). My colleague recently pointed out that permission is not enough and input should be secured (f.e. regexp) as well even for admin. Is that really necessary? Should we count with scenario where admin (with rights to delete all user's folders) wants to hack virtual machine?
So I've a VM that has SSH login. In this machine I only want one user ( lets say admin) to be able to login in via SSH.
Ive changed the sshd_config and added the AllowUsers admin directive. The problem is that I can still login to the machine with the user user, for example.
The host is a Ubuntu server and I'm accessing it via vSphere Client.
Is there anything I'm missing here?
I need to allow certain users limited access to the lab server. The server is RHEL 5.6. However, I don't want to give them the root access. Basically, we have configured a LDAP server where all the users have centralized NFS and LDAP login from any of the client machines in the network. So, the LDAP users home area is located in /home/users in the server. I need to give access to only this folder to a certain user.
If I edit the visudo file and add the following line in the RHEL server, will I be able to accomplish what am looking for?
user1, %operator ALL= /home/users
When you are authenicating users with ldap and nfs mounted share, as such users of ldap or without ldap would be restricted to work in their home directory only.

Basically, as you giving all users access as users not as root hence all users will not have root access either using local authentication or remote authentication. I hope the users don't know your root password. :)
SUDO is used only when you want to give some users privilege to run the command as root like a normal user will not be able to do the command "service network restart" but if you allow the user have sudo privileges, he will be able to do it.
