#
# NOTE: If you're not using authentication binds, you'll need to give
# dovecot-auth read access to userPassword field in the LDAP server.
# With OpenLDAP this is done by modifying /etc/ldap/slapd.conf. There should
# already be something like this:

# access to attribute=userPassword
#        by dn="<dovecot's dn>" read # add this
#        by anonymous auth
#        by self write
#        by * none

# LDAP URIs to use. You can use this instead of hosts list. Note that this
# setting isn't supported by all LDAP libraries.

# Leave it commented out to bind anonymously (useful with auth_bind=yes).

# Password for LDAP server, if dn is specified.
dnpass = {{ ldap_bindpw }}

# Use SASL binding instead of the simple binding. Note that this changes
# ldap_version automatically to be 3 if it's lower. Also note that SASL binds
# and auth_bind=yes don't work together.
#sasl_bind = no
# SASL mechanism name to use.
#sasl_mech =
# SASL realm to use.

# SASL authorization ID, ie. the dnpass is for this "master user", but the

# Use authentication binding for verifying password's validity. This works by
# logging into LDAP server using the username and password given by client.
# The pass_filter is used to find the DN for the user. Note that the pass_attrs
# is still used, only the password field is ignored in it. Before doing any
# search, the binding is switched back to the default DN.
auth_bind = yes

# If authentication binding is used, you can save one LDAP request per login
# if users' DN can be specified with a common template. The template can use
# the standard %variables (see user_filter). Note that you can't
# use any pass_attrs if you use this setting.
#
# If you use this setting, it's a good idea to use a different
# dovecot-ldap.conf.ext for userdb (it can even be a symlink, just as long as
# the filename is different in userdb's args). That way one connection is used
# only for LDAP binds and another connection is used for user lookups.
# Otherwise the binding is changed to the default DN before each user lookup.
#
# For example:
#   auth_bind_userdn = cn=%u,ou=people,o=org
#
#auth_bind_userdn =

# LDAP protocol version to use. Likely 2 or 3.
#ldap_version = 3

# If you wish to avoid two LDAP lookups (passdb + userdb), you can use
# userdb prefetch instead of userdb ldap in dovecot.conf. In that case you'll
# also have to include user_attrs in pass_attrs field prefixed with "userdb_"
# string. For example:
#pass_attrs = uid=user,userPassword=password,\
#  homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid

# Filter for password lookups
#pass_filter = (&(objectClass=posixAccount)(uid=%u))
