PAM_cracklib Error, dict error

I am using a Linux From Scratch System and am now busy building additional software with the Beyond Linux From Scratch instructions.

I installed Cracklib, Linux-PAM and Shadow.
While testing PAM I got some errors.
I ran passwd and got this error:
passwd: Critical Error - immediate abort
Enabling the debug-feature of I got an extra line of error.
Passwd now returns this:
PAM-Cracklib[29810]: dict path ''[.pwd] is invalid
passwd: Critical Error - immediate abort[
I understand that this must be terribly wrong, but luckily I still have a good working Linux-system besides my Linux From Scratch.

Has someone got an idea of what could be wrong.

Thanks in advance for the help,

P.S. I hope this is enough information If not, just ask for more.

Take a look at the Makefile for cracklib source. In it you should see a variable defining the path to the cracklib dictionary (DICTPATH "/some/path/to/dictionary"). Make sure that's the correct path. If all went properly during the compile, then it should have created:
Make sure these exist too (note: they can be in /usr/lib/ instead). Also, take a look at the cracklib README for more info.

Thanks for the help, but I have figured it out now.

I did as you suggested: looking in the README of cracklib and I specified a DICTPATH to comply with where it already was installed.
I reinstalled Cracklib several times, but that didn't work.

So the fault ought to be in my PAM install.
After searching in the Configure file and editing DICT_CANDIDATES (or something like that) to also include my DICTPATH ,
things work splendid.

I tend to be a bit stupid sometimes. I follow instructions from the BLFS-e-book as I mentioned before.
Making my previous version of PAM I must have mistyped the command to edit DICT_CANDIDATES with sed.

So it works now.
Thanks for the help,

hi, I'm having the same problem; I checked dict path but it seems ok. How can I enable debug feature of cracklib to see more detailed output?

ran a little command

I took a text file 'list' put in 'abcd' as its contents and ran the command
create-cracklib-dict list
It worked!!
Must have got something to do with the passwd's feature where it tells you if your password is a dictionary word or not.
