# ldap2dns(1)

LDAP based DNS management system

## NAME

ldap2dns - LDAP based DNS management system

## SYNOPSIS

**ldap2dns\[d\]** \[*-D binddn*\] \[*-b searchbase*\] \[*-o data\|db*\] \[*-h host*\] \[*-p port*\] \[*-w password*\] \[*-L\[filename\]*\] \[*-u numsecs*\] \[*-v\[v\]*\] \[*-V*\]\

## DESCRIPTION

This manual page documents briefly the **ldap2dns** commands. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page yet.

**ldap2dns** is an efficient, administration friendly way to maintain DNS information and distribute DNS records to multiple primary DNS servers running **djbdns** or **BIND**

## OPTIONS

A summary of commanline options is included below.

- **-D binddn**

  Use the distinguished name binddn to bind to the LDAP directory.

- **-w bindpasswd**

  Use bindpasswd as the password for simple authentication.

- **-b**

  Use searchbase as the starting point for the search instead of the default.

- **-o data**

  Generate a "data" file to be processed by **tinydns-data**

- **-o db**

  For each zone generate a "\<zonename\>.db" file to be used by **named**

- **-L\[filename\]**

  Print output in LDIF format for reimport.

- **-h host**

  Hostname of LDAP server, defaults to localhost.

- **-p port**

  Portnumber to connect to LDAP server, defaults to 389

- **-u numsecs**

  Update DNS data after numsecs. Defaults to 59 if started as daemon.

  Important notice: data.cdb is rewritten only after DNSserial in DNSzone is increased.

- **-e exec-cmd**

  This command is executed after ldap2dns regenerated its data files.

- **-v**

  Run in verbose mode.

- **-vv**

  Run in even more verbose mode.

- **-V**

  Print version and exit.

## ENVIRONMENT

**LDAP2DNS\_UPDATE** The LDAP2DNS\_UPDATE environment variable sets the time interval in seconds to update DNS data. This variable is overridden by -u option.

**LDAP2DNS\_OUTPUT** Specify the type of output. It may be set to 'data' so that its output may be used by tinydns. It may be set to 'db' so that its output may be used by 'named'. This variable is overridden by the -o option.

**TINYDNSDIR** The root-directory used by tinydns, ie. the one in which to tinydns expects its 'data'-file.

## FILES

/etc/openldap/ldap.conf\
 Options specified here fulfil the same purpose as for other ldap-tools.
