# that are defined in the smb.conf configuration file. You should then start with this configuration
# file. You will also need the SID for your samba domain: set up the controler domain before using

# If not defined, parameter is taking from \"net getlocalsid\" return

# Domain name the Samba server is in charged.

# LDAP Configuration

##############################################################################
# Notes: to use to dual ldap servers backend for Samba, you must patch
# Samba with the dual-head patch from IDEALX. If not using this patch
# just use the same server for slaveLDAP and masterLDAP.
# Those two servers declarations can also be used when you have
# . one master LDAP server where all writing operations must be done
# . one slave LDAP server where all reading operations must be done
# (typically a replication directory)
# Slave LDAP server
# Ex: slaveLDAP=127.0.0.1
# If not defined, parameter is set to \"127.0.0.1\"
slaveLDAP=\"$ldap_slave_server\"
# Slave LDAP port
# If not defined, parameter is set to \"389\"
slavePort=\"$ldap_slave_port\"
# Master LDAP server: needed for write operations
# Ex: masterLDAP=127.0.0.1
# If not defined, parameter is set to \"127.0.0.1\"
masterLDAP=\"$ldapmasterserver\"
# Master LDAP port
# If not defined, parameter is set to \"389\"
masterPort=\"$ldapmasterport\"
# Use TLS for LDAP
# If set to 1, this option will use start_tls for connection
# (you should also used the port 389)
# If not defined, parameter is set to \"1\"
ldapTLS=\"$ldaptls\"
# How to verify the server's certificate (none, optional or require)
# see \"man Net::LDAP\" in start_tls section for more details
verify=\"$cert_verify\"
# CA certificate
