I have 200.000 users. The most part only have email service. The file /etc/passwd es very, very long... but es necessary for IMAP server to check the home directory for every user.
nss_mysql is the only solution? Now, I have mysql to auth users for proftpd & apache via PAM (pam_mysql) Sendmail can't delivery emails to not existents users (it check /etc/passwd). IMAP server need /etc/passwd for check user & home dir. With pam_mysql check the user but not the home dir. Any solution for only-email users without /etc/passwd file??? How can to have many users easy? Joaquin Ferrero [EMAIL PROTECTED]
