[Dovecot] dovecot-ldap.conf for usernames/homes/UID/GID
hi there, I?m getting such a headache today, I?ve added myself to three mailing lists trying to figure this out, okay here it goes. I?ve got a Fedora Core 4 box running dovecot imap, squirrel mail, postfix, samba/winbind. I?m running winbind to authenticate against Active Directory, I?ve edited my ?/etc/pam.d/dovecot? pam module so to let my users login with there Active directory password, but squirrel mail wont let them I think, let me stress the term, ?think? is has something to do with there home directories, because I have some local users as well, they can login no issues & my users with the same usernames on unix and ADS can login with there ADS passwords Now I?m looking at the dovecot webmin module and I see that ?Data source for users, homes and Ids? is set to use ?Standard unix username database?. There is now option of PAM like in ?Password authentication source?. Although I do see LDAP, using config file. Can I set that to query Active directory ldap database and go there Data source for users, homes and Ids?? If I can can someone tell me how to, if not can someone tell me what I need to do? Here is what I have so far with my /etc/dovecot-ldap.conf hosts = senior-server.school.cathedral.qld.edu.au:389 dn = cn=administrator,cn=users,dc=school,dc=cathedral,dc=qld,dc=edu,dc=au dnpass = wwvH at cs ldap_version = 3 base = dc=school,dc=cathedral,dc=qld,dc=edu,dc=au deref = never scope = subtree user_attrs = uid,homeDirectory,,uid,uidNumber,gidNumber user_filter = (&(objectClass=posixAccount)(cn=%u)) pass_attrs = uid,userPassword pass_filter = (&(objectClass=posixAccount)(uid=%u)) CRYPT default_pass_scheme = CRYPT user_global_uid = 100 user_global_gid = 100

[Dovecot] dovecot-ldap.conf for usernames/homes/UID/GID
As time goes on I'm convinced more and more the problem is that I can't make the home directory when I login into squirrel mail ... Has anyone ever incounted this before? Q1. Can dovecot use it's LDAP configuration to get information from Active Directory? if so can someone show me and example dovecot-ldap.conf file? Q2. To this me seams like just virtual user scenario, in virtual users how do you get a home directory for mail to be stored in automatically? Q3. In my /etc/pam.d/dovecot pam module (shown below) it requests that you make a home directory, when i use this in my sshd pam module and login i make a home directory, when i do it via squirrel mail it dosn't make a home directory, why? auth required pam_winbind.so account required pam_winbind.so session optional pam_mkhomedir.so Q4. Here is both my configuration files, can someone tell me what i'm doing wrong? /etc/dovecot-ldap.conf hosts = server2000.mydomain.com.au:389 dn = cn=administrator,cn=users,dc=mydomain,dc=com,dc=au dnpass = password ldap_version = 3 base = dc=mydomain,dc=com,dc=au deref = never scope = subtree user_attrs = uid,homeDirectory,,uid,uidNumber,gidNumber user_filter = (&(objectClass=posixAccount)(cn=%u)) pass_attrs = uid,userPassword pass_filter = (&(objectClass=posixAccount)(uid=%u)) CRYPT default_pass_scheme = CRYPT user_global_uid = 100 user_global_gid = 100 /etc/dovecot.conf #base_dir = /var/run/dovecot/ protocols = imap imaps imap_listen = [::] pop3_listen = [::] #imaps_listen #pop3s_listen #ssl_disable = no #ssl_cert_file = /usr/share/ssl/certs/dovecot.pem #ssl_key_file = /usr/share/ssl/private/dovecot.pem #ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat #ssl_parameters_regenerate = 24 #disable_plaintext_auth = yes log_path = /var/log/dovecot.log #info_log_path #log_timestamp = "%b %d %H:%M:%S " login_dir = /var/run/dovecot-login #login_chroot = yes login = imap #login_executable = /usr/libexec/dovecot/imap-login #login_user = dovecot #login_process_size = 32 #login_process_per_connection = yes #login_processes_count = 3 #login_max_processes_count = 128 #login_max_logging_users = 256 login = pop3 #max_mail_processes = 1024 #verbose_proctitle = no #verbose_ssl = no #first_valid_uid = 500 #last_valid_uid = 0 #first_valid_gid = 1 #last_valid_gid = 0 #mail_extra_groups valid_chroot_dirs = /home default_mail_env = maildir:~/Maildir #mail_cache_fields = MessagePart #mail_never_cache_fields #client_workarounds #mailbox_check_interval = 0 #mailbox_idle_check_interval = 30 #mail_full_filesystem_access = no #mail_max_flag_length = 50 #mail_save_crlf = no #mail_read_mmaped = no #maildir_stat_dirs = no #maildir_copy_with_hardlinks = no #maildir_check_content_changes = no mbox_locks = fcntl #mbox_read_dotlock = no #mbox_lock_timeout = 300 #mbox_dotlock_change_timeout = 30 # umask to use for mail files and directories #umask = 0077 #mail_drop_priv_before_exec = no #imap_executable = /usr/libexec/dovecot/imap #imap_process_size = 256 #imap_use_modules = no #imap_modules = /usr/lib/dovecot/imap #pop3_executable = /usr/libexec/dovecot/pop3 #pop3_process_size = 256 #pop3_use_modules = no #pop3_modules = /usr/lib/dovecot/pop3 auth = default auth_mechanisms = plain #auth_realms #auth_default_realm auth_userdb = ldap /etc/dovecot-ldap.conf auth_passdb = pam #auth_executable = /usr/libexec/dovecot/dovecot-auth #auth_process_size = 256 auth_user = root #auth_chroot #auth_count = 1 #auth_username_chars abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ #auth_anonymous_username = anonymous #auth_verbose = no #auth_debug = no #auth = digest_md5 #auth_mechanisms = digest-md5 #auth_realms #auth_userdb = passwd-file /etc/passwd.imap #auth_passdb = passwd-file /etc/passwd.imap #auth_user = imapauth #auth_chroot # simply set "auth_methods = plain digest-md5" "/etc/dovecot.conf" 487L, 20333C -----Original Message----- From: dovecot-bounces at dovecot.org [mailto:dovecot-bounces at dovecot.org]On Behalf Of Paul Matthews Sent: Thursday, 12 January 2006 3:30 To: dovecot at dovecot.org Subject: [Dovecot] dovecot-ldap.conf for usernames/homes/UID/GID hi there, I?m getting such a headache today, I?ve added myself to three mailing lists trying to figure this out, okay here it goes.

Like what's written to the log files when a user tries to authenticate? There are a number of "verbose", "debugging" and "logging" options in dovecot.conf - you need to enable them & `tail - f` logfiles (I checked /var/log/messages & /var/log/mail when I had this problem). LDAP is irrelevant - a complete clupea rubra - when authenticating using WinBind. Winbind is not the same as Active Directory, although confusingly it seems to allow Active Directory users to authenticate. I think this is because on Windows server, by default, Domain users are also AD users, and you're actually authenticating against the Domain (not the AD) when you authenticate using WinBind. To authenticate using WinBind you'll need something like: In /etc/dovecot.conf : passdb pam { args = "-session *" } In /etc/pam.d/imap: #%PAM-1.0 auth required /lib/security/pam_winbind.so account required /lib/security/pam_winbind.so AD users need a store directory in which to keep their email - Dovecot will fail if they have no home directory. As I recall WinBind will return a suitable path for their home directory - the path where it'd expect them to be - but unless you have created that directory manually then Dovecot will crap out. IMHO the best way to resolve this is by using pam_mkhomedir - it'll create that home directory if it doesn't exist upon user authentication. I have implemented a system like this within the last 2 or 3 weeks and also had some problems with it. If you search my postings to the list you will see my configuration documented quite clearly and you should be able to see how I resolved my issues. I think you will be able to resolve all your issues by following them. Stroller.
