Hi all:

I have a FTP server combined with samba server. Pam_smbpass.so is used =
to provide authentication. Everything works fine in the beginning. But =
after a period of heavy access from FTP, the login will fail. I found =
the problem is resulted from secrets.tdb. It became an empty file (I use =
tdbdump to check the content). Pam_smbpass.so rejected the =
authentication when it can=A1=A6t check the SID in the secrets.tdb. My =
samba version is 3.0.25c. Previous version is 3.0.21c, and it did not =
have the problem.

Thanks for all advice,

Latrell.
