[csw-users] cups 1.2.7 401 Unauthorized

[Gérard Henry]

hello,
i installed cups 1.2.7 on solaris 10 x86 U3.
i'm using http://localhost:631 to add a usb printer, but when cups ask 
for passwd, it failed, even with machine root passwd.
I tried to give a password witch lppasswd, which writes in 
/opt/csw/etc/cups/passwd.md5
in error.log, i got:
E [01/Feb/2007:14:58:34 -0100] CUPS-Add-Modify-Printer: Unauthorized
E [01/Feb/2007:14:58:38 -0100] cupsdAuthorize: pam_acct_mgmt() returned 
7 (Permission denied)!

what's the matter?

thanks for help,

gerard
