I think you must patch your Solaris 10, then root is no longer exempted from the complexity rules.
man passwd on an old Solaris 10 says:

Quote:

In the files case, super-users (for instance, real and
effective uid equal to 0, see id(1M) and su(1M)) can change
any password. Hence, passwd does not prompt privileged users
for the old password. Privileged users are not forced to
comply with password aging and password construction
requirements. A privileged user can create a null password
by entering a carriage return in response to the prompt for
a new password.

While a newer Solaris 10 says

Quote:

The passwd command does not prompt authorized users for the
old password.
...
By default, even users authorized to change the password of
other users must comply with the configured password policy.
See pam_authtok_check(5).

This article suggests the change happened with Solaris 10 8/11.

BTW if you set the minimum password length to 8 then in fact you lower the security somewhat if you have CRYPT_DEFAULT=__unix__ in /etc/security/policy.conf because it always limits the maximum password length to 8.
So you should change it to CRYPT_DEFAULT=1 (1 or 2a or md5) to allow longer passwords! It also will create longer crypts in /etc/shadow, but can still understand the existing short Unix crypts.

SHADOW(5)							File Formats Manual							 SHADOW(5)

NAME

       shadow - encrypted password file

DESCRIPTION

       shadow contains the encrypted password information for user's accounts and optional the password aging information. Included is

	    Login name

	    Encrypted password

	    Days since Jan 1, 1970 that password was last changed

	    Days before password may be changed

	    Days after which password must be changed

	    Days before password is to expire that user is warned

	    Days after password expires that account is disabled

	    Days since Jan 1, 1970 that account is disabled

	    A reserved field

       The  password  field must be filled. The encryped password consists of 13 to 24 characters from the 64 characters alphabet a thru z, A thru
       Z, 0 thru 9, . and /. Optionally it can start with a "$" character. This means the encrypted password was generated using another (not DES)
       algorithm. For example if it starts with "$1$" it means the MD5-based algorithm was used.

       Refer to crypt(3) for details on how this string is interpreted.

       The  date  of  the  last  password change is given as the number of days since Jan 1, 1970. The password may not be changed again until the
       proper number of days have passed, and must be changed after the maximum number of days.  If the minimum number of days required is greater
       than the maximum number of day allowed, this password may not be changed by the user.

       An  account is considered to be inactive and is disabled if the password is not changed within the specified number of days after the pass-
       word expires.  An account will also be disabled on the specified day regardless of other password expiration information.

       This information supercedes any password or password age information present in /etc/passwd.

       This file must not be readable by regular users if password security is to be maintained.

FILES

       /etc/passwd    - user account information
       /etc/shadow    - encrypted user passwords
