I am trying to set up Ubuntu like I had on my windows PC. I have my account, my wifes account and my kids account. I want passwords set for both myself and my wife but I don't want the kids to be required to have a password to log in. When setting up Ubuntu, it looks like it was all or none. I have dabbled with Linux off and on for years and am sure there is a way to set this up but I have no idea how.
View 8 RepliesI upgraded from 10.10 to 11.04 (32 bit) with a clean install as the "upgrade" option in update manager failed. I'm setting up the system again and want to restore the backup I took prior to upgrading, however due to the upgrade I don't want to just re install everything. The following have been backed up
/etc
/home
/usr/local
/var
Now there are various things that are different such as firefox 3.x has become firefox 4 Open office is gone, long live LibreOffice, my proprietary Nvidia drivers don't seem to be trusted yet, all the repositories will be different etc. I will re install all the applications fresh from the software centre, but I would like to restore all the users and passwords and their home directories,
So I don't I want to restore /etc or /usr/local en masse. I guess /var is not worth restoring either /home gets me their files but how do I restore the users and passwords? (there are about 8 registered users some of whom have different privileges) and the user ID need to be the same as they all access a NAS through nfs)
I have Fedora 10 installed. I want my users to be able to use any password they want. So I edited /etc/pam.d/system-auth, the password section.
Was:
Code:

password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok
password required pam_deny.so

I'm configuring a CentOS 5.4 workstation. I have been able to apply most of the security that is required. I have met all but one logging requirement. How do you get the count of old passwords associated with users? I don't need to see their passwords just how many times they have changed them. I have set remember to 24 in the /etc/pam.d/system-auth file. I don't know where the file is that contains this information.

I did:

I have an old server running CentOS 5. The encription method used was the default MD5 for the shadow file. I would like to migrate the server to Debian Squeeze which uses SHA512. I have already copied the passwd, group and shadow file with the user accounts information but the Debian machine doesn't let the users login. I have already looked in the pam files to make it accept the MD5 encryption without any luck. how can i migrate the users without resetting their passwords?

I am using squid + dansguardian for web and content filtering. And it is working fine. I am forcing users to use proxy through browser configuration. Now I am planning to add another layer to controlling access using ncsa_auth program. I know it is not the most secured but I am fine with it. Plain passwords are fine with me.
I will be giving users some default passwords but I want some program for allowing users to change the passwords for the respective users if they want. Is there any perl script or something web based for the purpose that anyone is using or know of?
just now i have installed squid, it works fine with authentication . I created this authentication in a simple text file by using htpasswd . my question is that is there any web based simple page to change passwords of squid users, because each and every time i cant give direct access to server for my squid users .

View 6 Replies View RelatedI'm planning to centralize users and passwords and also create controls for user access to some equipment, for example, Linux Servers, Switches, routers and firewalls. In case of failure of the link between the ACS and AD or equipment to the ACS, this device would use local username and password.
At the moment, my AD structure is a Microsoft, Cisco ACS servers and Linux Standalone. I wish that both linuxs servers and network equipment were authorized by Cisco ACS on the accounts that are in Microsoft AD.
The configuration of the Cisco ACS to use the AD is done and no problems, the network equipment is OK too, but am having difficulties configuring the server for this solution.
I am looking for ideas for getting windows users into an ldap server. I am currently running a Linux server for my department and need to create an LDAP server which mirrors the username/password information for all of us as they are stored in the windows server here. I have the openldap server up and running on Ubuntu 8.04 and it works great; I now need to find some way to import user info into this from windows. I've seen discussions of using ldifde.exe to export the AD users into an ldif file. Is this the simplest way to go about it?
Our Linux server is currently providing us with much needed services using apache, and apache is authenticating using LDAP to our windows server (Using our windows username / password is required functionality). This windows server has some problem which causes it to delay for inordinate amounts of time between authentication requests and responses. The situation is such that this problem will not be addressed by IT staff. However, I have control over the Linux server so I am looking to just mirror the windows server on an LDAP server of my own. I could get away with updating the passwords in the Linux server.
I wonder if it is possible to have two passwords for one user account in 9.10. I have a long login password (5 words about 45 characters with spaces caps). I would like to set a shorter password for Authentication, sudo, etc. While retaining the original for logging in.In short:Have long password to login to computer.Have short password for everything after login.
View 6 Replies View RelatedDon't worry, I know - that title probably makes this question seem way more complicated than it actually is. Here's the situation: I have a server running SLES10 with a samba share set up on it. I created a username in Samba and Linux for myself, can access the share, permissions are fine, yadda yadda. Now I want to give about 100 more people access to it.
I have active directory running which users log into and I'd like them to be able to use their active directory passwords to authenticate to the share, rather than have me create 100 individual Samba/Linux accounts. In the future the AD server will be changing over to server 2008 but I'll cross that bridge when I get there. It would be equally effective if I could pull AD passwords from AD and "auto-create" the associated Linux/Samba users. Any ideas or could someone point in the right direction?
If I want to add Windows & Mac users as Samba users, must I first add them all as Ubuntu users? If so, since none of the other users will actually be working on the Ubuntu Server, how do I disable the other non-admin users on the Ubuntu Server login screen. I am using Webmin to administer some server settings, and command line for others.

View 5 Replies View RelatedSamba up and running on my pc. pc runs FC12 with kde. A laptop has win vista. The pc can access the shares on the laptop but the laptop has authentication issues to access the pc. Note that windows doesnt enforce authentication forincoming network connections.Using the system-config-samba util i tried to map a windows user to the unix user "feduser". The laptop (named LAPPY) has a user (lapuser) which has on windows no password.What should I tell samba config what the windows username should be? lapuser or LAPPYlapuser doesnt work because when accessing the pc via the laptop, the authentication fails. The only auth that is successful is when choosing the same winusername as the unix username.
Secondary, id like to setup the laptop so that the user doesnt have to provide a name and password, or at least not more then once in the lifetime of the laptop. Note that you cant provide an empty password to system-config-samba. How is that possible?
Strange but not really on issue imho:the samba - KDE control module(kcmshall4) (and the smb.conf) shows 2 shares: the homedirs and the data dir the samba server configurator (system-config-samba) shows only the datadir.
I work as an system administrator for AIX and Linux servers. We have an FTP server running in Linux which has shared folders to Windows domain using Samba. The new requirement is to map users created to Linux machine to Windows users in such a way that, when a user logins into Windows machine with an ID say "X123" in domain "TEST", his access control to the samba shares should reflect based on the same user ID created in Linux machine.(FYI. Both the Windows and LINUX machines are in same network and domain). Please let me know the step by step procedure to configure Linux machine (smb.conf entries or any new file to be created for user mapping) to identify Windows user Login and provide access restrictions accordingly.
