MIT Kerberos Password Checking
|Reported by:||Randy McMurchy||Owned by:|
Description (last modified by )
The MIT Kerberos package has code which will use a dictionary file to check for strong passwords.
I suggest that the MIT Kerberos instructions add an "Additional Download" section to download the CrackLib dictionary
download: http://prdownloads.sourceforge.net/cracklib/cracklib-words.gz MD5 sum: d18e670e5df560a8745e1b4dede8f84f Size: 4.4 MB
and install it using the CrackLib instructions
install -v -m644 -D ../cracklib-words.gz \
gunzip -v /usr/share/dict/cracklib-words.gz && ln -v -s cracklib-words /usr/share/dict/words
then provide instructions in the configuration section to create a kdc.conf file and add the dict_file flag to the file.
This would then install MIT Kerberos using strong password checking as the default. Unfortunately, I cannot find a way to use an additional file (similar to the CrackLib cracklib-extra-words file) to use additional, site-specific words.
Perhaps a mention to add these site-specific extra words to the CrackLib dictionary would suffice.
Exectuve Summary of this bug:
If a site is worried (smart enough) to use a Kerberos authentication system to provide strong and encrypted authentication, but does not force users to use strong passwords, the security of the system is drastically reduced, and can easily be compromised.
