I have Samba 3.0.34 on OpenSuSE 10.3 (RPM from ftp.sernet.de) on a x86-server using a local OpenLDAP as the passdb backend.
In smb.conf I have configured a custom sync script:
unix password sync = yes
passwd chat timeout = 200
passwd chat debug = yes
passwd program = /usr/local/bin/smb_pw_sync %u
ldap passwd sync = no
I try to change the users password from a windows client (Windows XP SP3)
Sorry, I pushed the commit-button too early.
The complete description is in bug #6411.
