[Samba] Strange automount problem with samba & LDAP

Hi all,

Finally I've found that in auth/auth.c, 'check_ntlm_password' function 
stat works as expected, and I added some code to get user's home 
directory from LDAP and do a stat to that directory. Now everything 
works as expected. Is it possible that samba changes system's default 
encoding in somewhere, because system call 'system("ls -l 
/home/stf4/yusuf")' also did not worked.
