As i have discovered, the "unix passwd sync" feature of samba does'nt work with
2.2.x kernels. it seems so, that the samba calls the unix "passwd" program,
gives it the new password 2 times, and with 2.2.10 kernel, the passwd program
crashes. It happens undex Rh 5.2 and 6.0. All is working perfectly with
2.0.3[5,6]. Is this samba, kernel or perhaps Redhat related problem? I have
included my samba log and strace output from "passwd". Please Cc: all replies
to jaanus@hwg.edu.ee
