Hello, Some weeks ago I reported my troubles with mixed-case passwords. I thought that using the option "password level" would solve my problems. Unfortunately I have ran into difficulties. Our students passwords are eight caracters long, with at least one number, one minor letter and one capital letter. I have set "password level = 6" (since there can be a maximum of 6 capital letters). Now I tried to logon but I did NOT work for passwords with two or more capital letters. The cause?: I looked in /var/log/messages and found strange errors there: Apparently PAM_unix caused a lot of authentication failures (all the passwords that are wrong) and apparently there is a maximum number of times that pam will try to authenticate. This is what I think because passwords with only one capital letter work fine (of course they also generate some authentication failure messages). Does anyone know whether there is a maximum number of times that PAM tries the authentication? Are there other modules available. The same problem exists with the pam_pwdb.so module. An example: Jul 5 15:35:13 linsam2 PAM_unix[28971]: authentication failure; (uid=0) -> m9713423 for samba service Jul 5 15:35:36 linsam2 last message repeated 12 times I use pam_unix.so in /etc/pam.d/samba. Does anybody whether this is necessary for Samba to work? (this configuration file is installed standard in Redhat) Yes, it is necessary, without this file it's not possible to login. Like mentioned on previous occasions I do not use /etc/smbpasswd (too slow for 25000 users because it is a non-indexed file). Another error which I cannot explain: [root@linsam-14 samba]# smbclient -L linsam-14 ****** Password: Anonymous login successful Domain=[STUDENT] OS=[Unix] Server=[Samba 2.0.7] tree connect failed: code 0 Any help would be greatly appreciated!!!
