I saw the header for libsmbclient.so, and it looks pretty basic - file access, print job access, share access, but no password modification. Is there a chance this will be modularized into the library in the future? i.e.: add this call to the library: int smbc_change_passwd( char* un, char* wg, char* oldpw, char* newpw ); Or at least something with a callback a-la smbc_init()? This would facilitate the pam_smbpass module to do remote password updates and authentication, looking for a semi-single-sign-on solution. Currently, I can do this and keep unix and smb passwords (mostly) in sync and authenticate through a centralized server. However there are some limitations which could be addressed by this such as doing all passwords on Samba. This of course is NOT preferable to Kerberos, but since no production Samba can do Kerberos V yet, I see few other options. Best Diego
