I strongly suggest to setup the user using # useradd -r man useradd ... -r This flag is used to create a system account. That is, a user with a UID lower than the value of UID_MIN defined in /etc/login.defs and whose password does not expire. Note that useradd will not create a home directory for such an user, regardless of the default setting in /etc/login.defs. You have to specify -m option if you want a home directory for a system account to be created. This is an option added by Red Hat. You are then still able to specify usual useradd options (such as defined UID etc.) In addition would I suggest to use sudo which will help you switch to this particular user (instead of su) Using sudo has also the benefit that each activity is logged and can therefore be traced back. In case you also need to have the ability of remote login using ssh can you use ssh private/public key to avoid password usage. (but I do not suggest that due to security issues ... or at least set it up correctly) Cheers, Simon >-----Original Message----- >From: redhat-list-bounces@xxxxxxxxxx >[mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Santosh Kumar >Sent: Wednesday, May 27, 2009 8:42 AM >To: General Red Hat Linux discussion list >Subject: Re: Unprivileged User's Account Without a Password > >You may try passwd -d <UserName> which will delete user >password and will >not ask at the time of login. > >On Wed, May 27, 2009 at 10:35 AM, Ka kkar <vijay1313@xxxxxxxxx> wrote: > >> On Wed, May 27, 2009 at 2:25 AM, Devarishi Kumar Mahadeva < >> dk_mahadeva@xxxxxxxxx> wrote: >> >> > Hi, >> > >> > >> > Can we have an unprivileged user's account without any >password such that >> > the user can still login and perform tasks in the same way >he or she >> would >> > do by entering a valid password. >> > >> > Well, as I am aware of it that when we create a user's >account by giving >> > the following command: >> > >> > #useradd <UserName> >> > >> > We don't have to set a password for that account at this >state.
