Hi

I've added the apostrophe character to auth_username_chars however authentication still fails. I'm using LDAP with the following details:

dovecot version 1.1.7 openldap client library 2.4.11

With auth_verbose = yes and auth_debug = yes set I see the following in the logs. Note the initial escaped apostrophe and the subsequent escaped escape in the filter!

----- start log ----- Jan 5 16:15:05 www-example1 dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=10.1.1.180 rip=10.3.96.60 lport=143 rport=48733 resp=<hidden>

Users without apostrophes can authenticate successfully. If I've missed anything please let me know.
