Require Password Match Regular Expression
This lets administrators restrict passwords to those that match a regular expression.
Figure 4-42. Allow UserID in Password
For example, this allows administrators to supply an expression like this:
[^[:digit:]\\\'\;\"\:\?\/\>\<\,\.\=\-].*([[:digit:]\\\'\;\"\:\?\/
\>\<\,\.\=\-]).*[^[:digit:]\\\'\;\"\:\?\/\>\<\,\.\=\-]
This expression specifies that the password must contain, but not start or end with, a numeric or
special character, where a special character is defined as any of the following: \";:?/><,.=-
Permitted regular expressions are of the type "RE_SYNTAX_POSIX_AWK". This specifies, among
other things, that special characters must be escaped using the backslash.
This policy defaults to an empty regular expression.
