Dear Tim Schafer,

Take a look at my sample dovecot-ldap.conf

hosts = localhost dn = cn=root,dc=ceylonlinux,dc=com dnpass = secret ldap_version = 3 base = dc=ceylonlinux,dc=com deref = never scope = subtree user_attrs = mail,homeDirectory=mailMessageStore,uidNumber=1003,gidNumber=1003 user_filter = (&(objectClass=user)(mail=%u)) pass_attrs = mail=user,userPassword=password pass_filter = (&(objectClass=user)(mail=%u)) default_pass_scheme = CRYPT user_global_uid = 1003 user_global_gid = 1003

Here I am using my own schema called "user", but in your case change it to inetOrgPerson or the schema name you are using.

I think the most common problem in this process is the ldap filter. Above in my configuration user_filter and pass_filter are used as ldap filters for querying user name and password. There I am using mail attribute.

gid and uid are belong to the user vmail.

May be this explanation will help you to figure out your problem

You can refer my article in the following link for further reference

Thank you Johannes,

By modifying auth_username_chars in dovecot.conf I was able to allow spaces in usernames.

I'm assuming it doesn't like the spaces. Any way around this?

You can set the allowed characters somehow. I forgot how, but check the annotated config file.

Also, I don't see any way to support the seperate username and userid where the username is for authentication and the userid is used for on disk pathname. Anyway to support this?

I know with SQL that's possible by just returning user= from the query, I guess LDAP as well. I think Timo just posted about this in some other ldap thread. Not quite sure though.

Sorry to be so vague, I just happened to have skimmed some messages that seem to related to this recently.

Is it possible to have local users with mail in maildir:%h/.maildir

and virutal users with mail in maildir:/home/exim/%u/.maildir

I seem to have authentication working for both local users and LDAP users. But I'm getting this error trying to access a virtual users mail.

Hi,

I'm migrating accounts from one server with dovecot mbox and pam nss-ldap authentication to a new server with dovecot maildir and mysql auth (no posix accounts).

My problem is the pop3 uidl format on the two servers are different, even though I'm using pop3_uidl_format = %08Xu%08Xv in both configs, I'm always re-downloading left messages on my test runs. Is there a way I could reuse the X-UID and X-IMAPbase headers on the converted mails. Issuing the UIDL command via pop3 always give a different result for the mbox and maildir spools.

The X-UID and X-IMAPbase headers are present in the converted mails. The first number of X-IMAPbase maps to the mail UIDVALIDITY and the second is the same as X-UID, the mail uid.

You'll have to make your conversion script create dovecot-uidlist file based on the X-IMAPbase and X-UID headers. There could be existing scripts to do that, but I'm not sure.
