[Solved] Password Length...

I realized just now that the maximum password length for Arch is 8 characters (thanks NSA, for helping me figure this out).  I'd like to increase that number to 16 characters (or more). 

I apparently suck ass at Googling.  Red Hat and Ubuntu come up when searched, but their solutions do not work for Arch (or I suck at applying their convention to Arch, which is probably the case). Any insight/help would be greatly appreciated.

[Edit]: I created a dummy user with the same passphrase and it meets refusal when I truncate the passphrase.  I've rebooted and truncated the passphrase for my normal account and I am able to logon with said truncated logon. 

Slept.

[Edit 2]: I solved this problem by changing the password as root.  I had changed my user password using sudo previously.  I have learned, thank you for your patience.

Re: [Solved] Password Length...

Ummm ... where are you getting that number from? My root p/w is well over 16 characters.

Re: [Solved] Password Length...

@60lpsdf250: Some websites impose limits on the password length, mainly because they are using an out-dated security system/being just plain silly.

Modern Operating systems don't have an upper limit on the password length. I think we would like to see where you got your information from.

I created a "passphrase" that is 7 words (27 characters) with spaces, capitals, and special characters.  I inadvertently messed up during a login and didn't complete the entire passphrase and was able to login.  When I realized this I tested the characters until I realized that 8 characters will logon.  I have 7 Arch boxes and every one of them respond the same way.

To clarify, this is when I turn my computer and am presented with the login prompt (I don't use a login manager and startx from command prompt).

There is no such limit. The problem lies elsewhere.

You probably messed up somewhere because I've been using 12+ character long passwords with Linux installations for at least 5 years and I've never seen anything like what you are claiming (I've never seen anything like what you're claiming in my time with computers).

EDIT: You can edit posts, saving another post being made.

Re: [Solved] Password Length...

My password is behaving correctly... hmm 23 characters long. I tried "accidentally" messing up the final character and, as expected, failed to login.

Are you using a special login setup, such as using PAM or NIS?

Re: [Solved] Password Length...

I also just tried this and get the expected refusal due to incorrect password. Isn't PAM standard?

So the login prompt is your virtual terminal login?

As everyone else says, there's no such limit there. How did you set up the password? 7 Arch boxes... if you used a script to set it up the problem probably lies there.
