cannot add users or change passwords
I have a red hat linux computer that has been up and running for almost 1 year. Last week it would not let me add any new users or change a password for an established user.
I am not sure why this machine would start doing this.
When I try to add a user it tells me give me an manipulation error.
When I try to add a new user, the error says that it cannot lock the password file.
I usually use vipw to check the user file but I cannot use this command any more on this machine. Since I have not seen this error before, I am stumped. I don't want to start over with this machine because of the user accounts that already running.
Any ideas or help would be appreciated.
