Hi,
I'm trying to configure dovecot to use LDAP authentication directly, and I'm having a bit of trouble. I have a somewhat unusual setup, in that I have an LDAP directory that has 3 OUs each of which have their own set of users, some of which overlap. As I was trying to figure things out, I was setting the search base in my /etc/dovecot/dovecot-ldap.conf.ext file which is referenced by /etc/dovecot/conf.d/auth-ldap.conf.ext file to
base = ou=%d,dc=thecrazyguys,dc=net
however, the resulting searches against the directory endup just dropping the %d, resulting in
ou=,dc=thecrazyguys,dc=net
which is invalid. On a whim, I tried a search base of
base = dc=%d,dc=thecrazyguys,dc=net
and found that it did correctly substitute in the variable, which would be correct, except that my ldap tree is set up with OUs and not an extra DC segment.
for whatever reason, it will do variable substitution for dc=%d, but not for ou=%d. this is certainly not documented, and seems like wrong behavior, since having an ou in a search base is valid.
I'm including configuration information below. Please let me know if I've missed including information that is required.
Thanks! Luke
