After further research I've changed the component (and title) to glibc as I believe the problem lies at the system level. I believe that this limit needs to be increased so as to provide a consistant "single sign on" facility where the single username is often an email address. glibc supports usernames longer than 32 characters (may I have your glibc version to confirm this) It seems like problem either in vsftpd or somewhere in between. Anyway I didn't manage to configure vsftpd to work with LDAP. Can you give me some configuration hints so I can reproduce this bug? in addition, I've figure out that it vsftpd which trims usernames to 32chars. Still looking for some test case with LDAP. Fixed in vsftpd-1.2.1-3E.2 |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.4.3) Gecko/20040924 MultiZilla/1.6.4.0b Description of problem: usernames are limited to 32 characters. Usernames longer than 32 characters do not successfully authenticate. Version-Release number of selected component (if applicable): vsftpd-1.2.1-3 How reproducible: Always Steps to Reproduce: 1.Have username longer than 32 characters (ours is in LDAP) 2.Try to use that username to authenticate an ftp session 3. Actual Results: login fails with a "Login failed" error message. Expected Results: login is successful Additional info: The long username is supplied via LDAP - vsftpd is configured to use PAM. The length of the username is due to it's email format, ie the username is an email address.
