Samba Password changes

[Darryl Bond]

Hi,
    I have set up a Samba server Ok and I want to allow the windows
users to change their passwords. I have done the following.
Sun Solaris 2.51
Samba 1.9.17p5

Makefile extract

# This is for SUNOS5.4 and later (also known as Solaris 2.4 and later)
# contributed by Andrew.Tridgell at anu.edu.au
 FLAGSM = -DSUNOS5 -DSHADOW_PWD -DNETGROUP -DFAST_SHARE_MODES
-DALLOW_CHANGE_PASSWORD
 LIBSM = -lsocket -lnsl
 AWK = nawk

The Solaris box is stand alone (Not using nis+)

I have set up the smb.conf file with
security = user
passwd program = /usr/bin/passwd %u
passwd chat = "*Old password*" %o\n "*New password*" %n\n  "*Re-enter
new  password*" %n\n


When I try to change the password from a Win95 box I get an error

This request is not supported by network

Otherwise the installation works fine

Thanks in advance
