Login problem: 'Authentication Failed'
When iam logging into redhat linux, its giving 'Authentication Failed' message.
I tried to get in to the interactive mode while booting and after giving my root password, i got prompt as below
I tried 'fsck' and its getting out with out doing file system check.
And i also tried to create a new user by all ways , like
(RepairFileSystem)# adduser naren
(RepairFileSystem)# useradd naren
(RepairFileSystem)# useradd -d <username> -p <password> -L | -U
and iam getting message as
'unable to lock password'
even after trying -L and -U options
So please help me by giving some solution or hint (advantageous) in solving my problem
Thank you very much in advance.
