If the login is failing because you need a passwordless login by a script, and the script is failing - it is probably because the ADMCHG flag is still set.
Note: passwordless is not recommended. Use the following at your own (companies) risk!
In short, you need pwdadm -f NOCHECK username to disable password checks to be sure you can enter a NULL password, and you will need to enter it again so that the ADMCHG (admin change) flag is cleared after you set the NULL password.
Note: You need to be root to perform the grep -p username /etc/security/passwd command

# cat /etc/shadow | grep mysql

yppasswd
yppasswd(1yp)yppasswd(1yp)Name
yppasswd - change password in yellow pages (YP) service.
Syntax
yppasswd [ name ]
Description
The command lets you change your password in the yellow pages (YP) map, a network data base service. Only you or the superuser can change
your YP password.
When you enter the command, the program prompts you for the old password and then for the new password. Note that the passwords are not
displayed on the screen.
Next, the program asks you for the new password again, to verify that you have typed it correctly. If you do not type the passwords cor-
rectly, you will receive an error message after you enter the new password.
Your new YP password must meet one of the following requirements:
o It must be a combination of at least six alphanumeric characters, or
o It must be a minimum of four characters, with at least one being non-alphanumeric, such as a control sequence.
The command does not change the YP password. This command only changes the local password file and not the YP master password file. See
Chapter 3 of the Guide to the Yellow Pages Service for further information.
Diagnostics
Please use a longer password
Your new password does not meet the minimum length requirement.
Mismatch- password unchanged
You misspelled your new password or its verification.
couldn't change passwd
Your new password can not be activated. It must be different from your old password and your login name.
