AIX: How to check which authentication method we are using for a user?


In /etc/security/user, we can set which authentication method we use for each user. for example:

test:
admin = false
rlogin = false
SYSTEM = "NONE"

I want to test whether SYSTEM=NONE (without ") is acceptable. How can I verify it? and How can we check which authentication mehtod we are using?

Thanks in advance.

Cool AIX authentication

According to IBM at

http://publib.boulder.ibm.com/infoce...entication.htm

you are using "No Authentication" when setting system=none.

Check the link it has good information about password and authentication.

thanks for your support.

But my point is if I set SYSTEM=NONE (without ""), does the system really turn off Authentication?, because the standard format is SYSTEM = "NONE".

Moreover, I want to check which authentication method (compat, auth1, auth2...) is being applied to a specific user.

thanks again

Hi,

My configuration setting under /etc/security/user is set up as follows:

default:

admin = false
login = true
auth1 = SYSTEM -- This sets normal password authentication as a default
SYSTEM = "compat" -- This sets the default to allow local plus NIS authentication


*** this section of the /etc/security/user file overides the defaults settings ***

johndoe:

admin = false -- ensures the user has no administrative rights
SYSTEM = "NONE" -- Turn off authentication for the user. The user enters the username at login but can enter anything for the password. Password cannot be blank. The password is not verify with this setting.

according to the link below you need both SYSTEM="NONE" and auth1=NONE to turn off all authentication. However, I still needed to enter at least one character for a password.

That was a good question!!

Thanks Hector, that's exactly the answer I want.
I am a newbie in Unix-based system, I really appreciate your help.
