Answer / mohammed mukram

Login incorrect: The most common cause of
anincorrectloginmessageisamistypedpassword.
Make sure the that correct password is being used,
and then attempt to enter it again. Remember that
passwords are case-sensitive, so you cannot
interchangeuppercaselettersandlowercaseletters

Permission denied : This message occurs when there are
login,
password, or NIS+ security problems. Most often,
anadministratorhaslockedtheuser’spasswordor
the user’s account has been terminated

Password will not work at lockscreen: A common error is to
have the Caps Lock key on,
which causes all letters to be uppercase. This does
not work if the password contains lowercase
letters

Noshell : theuser’sshelldoesnot
exist, is typed incorrectly, or is wrong in the /etc/passwd
file

and many more....

Answer / ramakrishna talluri

there are two reasons for this

1)the box is down

2)the nis issue

for both these you need to login from console and you need
to check whether the box is running or not if it is not
running boot

if it is running then there is an nis issue
trouble shoot this by checking /etc/hosts
ifconfig
nslookup
ypwhich -m
ypwhich
check the status of autofs and nis
