[zhengyibiao at vnet.citiz.net]

Hi: 
I am using freebsd5.2, because i have a large number of users counted by ten thousand, use the passwd file to store user accounts and password lead to unbearable delay. I want to know if freebsd support store accounts in places other than '/etc/passwd' file, best support mysql database for passwd database backend. 
any hints is welcome.
