docker-openwrt-ldap

A docker image for openldap based on OpenWrt x86_64 which writes data to a persistent Docker data volume at /data.

How to use

Give it two env vars:

  • LDAP_DOMAIN
  • LDAP_ROOTPW

and a volume to store the data:

docker run -e LDAP_DOMAIN=example.com -e LDAP_ROOTPW=secret mcreations/openwrt-ldap

How to import LDIF files

After importing the base ldap files, during startup, the startup script checks for LDIF files in the following folder to import them at database level 0:

/etc/openldap/schema-ldif-includes/*.ldif

/var/openldap-data/schema-ldif-includes/*.ldif

Then the system checks for ldif files in the following folders to import at database level 2:

/etc/openldap/ldif-imports/*.ldif

/var/openldap-data/ldif-imports/*.ldif

The file names in each folder are sorted alphabetically before import.

Debugging

Set the env var LAPDTOOLS_DEBUG_LEVEL to a numeric value corresponding to the bitwise OR of multiple of these flags:

Level   Keyword         Description
------  --------------  -------------------------------------------------------
-1      any             enable all debugging
0                       no debugging
1       (0x1 trace)     trace function calls
2       (0x2 packets)   debug packet handling
4       (0x4 args)      heavy trace debugging
8       (0x8 conns)     connection management
16      (0x10 BER)      print out packets sent and received
32      (0x20 filter)   search filter processing
64      (0x40 config)   configuration processing
128     (0x80 ACL)      access control list processing
256     (0x100 stats)   stats log connections/operations/results
512     (0x200 stats2)  stats log entries sent
1024    (0x400 shell)   print communication with shell backends
2048    (0x800 parse)   print entry parsing debugging
16384   (0x4000 sync)   syncrepl consumer processing
32768   (0x8000 none)   only messages that get logged whatever log level is set

Replication

To configure replication, use the following settings:

  • start the master with -e LDAP_IS_MASTER=true (default is false)

  • start the slave with -e REPLICATION_PROVIDER_URL=ldap://rep-provider:389 (defaut value is ldaps://replication-provider:389)

  • start the slave with --link ldap-master:replication-provider
