[Samba] quick pam_winbind.so question

[daniel.jarboe at custserv.com]

2.2.6 installed from rpm on rh 7.2 system...
I'm trying to use pam_winbind and apache's basic authentication to 
restrict access to certain directories served by apache.

It does work, but when I enter a wrong password I get this error in 
log.winbindd:
Plain-text authentication for user jarboed returned NT_STATUS_WRONG_PASSWORD

Is there a way that pam_winbind.so can encrypt the passwords rather than 
send them plaintext?

Thanks,
~ Daniel
