Sorry for the missing subject.
Hi,
I use a OpenLDAP for authentication. To authenticate a full DN as the user name must be used, like "cn=jim,ou=users,dc=example,dc=com". There are several domains, like example2.com and example3.com. I want to use Dovecot with ldap and >authentication binds. For testing I use "auth_bind_userdn = cn=%n,ou=users,dc=%d" and the user name must provide as "jim@example,dc=com". To allow the special chars ("=,") in user name, I extend "auth_username_chars". Now my questions. Exists a real chance to attack the ldap directory with the extended "auth_username_chars"? And it's possible to use authentication binds with the regular "auth_username_chars" and a provided user names like >"jim@example.com" in my special ldap directory structure?
Thanks in advance
