pam_unix Module Not Allowing Random String Passwords in Ubuntu 18.10
I just installed Ubuntuy 18.10 on one of my computers, and am trying to understand why a series of passwords are not working, even though they are completely random character strings.
I started by trying to change the initial password to the following character string: XB76cD_*P789_;Eqy10
I receive the following error and was prevented from using the password:
Try to avoid common words.
As far as I know, this string is not a common word in any language so I started to dig into it deeper to see why this password was not allowed.
The fresh installation is still using the default pam_unix module to validate changed passwords, so I looked in: /etc/pam.d/common-password , and did not see any rules that would make this password invalid.
I then started trying slight variations of the same password to dig a little deeper into why the random password was not allowed. I started to find slightly different variations of the password that were also not valid:
XB76cD_*P789_;Eqy12
X76cD_*P789_;Eqy12
[.] B76cD_*P789_;Eqy10
It seems as though there is a regular expression set somewhere that is preventing me from using a lot of passwords which should be valid. Does anyone have any idea as to what I should check next to be able to determine why these passwords are not valid?
