An updated vsftpd package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The vsftpd package includes a Very Secure FTP (File Transfer Protocol) daemon.
The vsftpd daemon sets a value of the RLIMIT_AS variable during its initialization phase. With Red Hat Enterprise Linux 6.1, the RLIMIT_AS value (100 MB) became insufficient which restricted LDAP users from authentication to the system using vsftpd. With this update, the initial RLIMIT_AS value has been increased to 200 MB, and vsftpd now can be used for LDAP authentication as expected.
All users of vsftpd are advised to upgrade to this updated package, which fixes this bug.
