It doesn't explain max= or maxlen= because there are no such options to
pam_unix!  There was once a 'max' option to pam_unix *documented*, but it
never worked and served no purpose.

Which complexity checks are you trying to disable?  The only one enabled by
default in pam_unix is the minimum password length requirement, which is
controlled with the 'min=' option.  There is also the 'obscure' option which
is turned on by default in the stock Ubuntu config.  All other password
strength checks are applied by the pam_cracklib module, not by pam_unix; you
can tune those with the various options described in the pam_cracklib
manpage, but if you don't want any strength checking, you should just remove
the libpam-cracklib package.
