Lately, I stumbled on a javascripted web page my employer 5 to 10
years ago used to suggest difficult passwords.  The rule, enforced by
LDAP was that a password must represent at least 3 of the 4 categories:

o minuscule
o numeric
o special
o majuscule

The recommended generator did all 4.  Of 8 characters (the enforced
minumum):

o 1-2 are minuscule
o 3-5 are numeric
o 6 is special
o 7-8 are majuscule

But is this an optimal defense against a brute-force search?
