zmprov Command Files

The zmprov command will accept commands from a file (or stdin) as input. Create a text file ("commands.zmp" for example) with the zmprov subcommands each on a line.

createDomain domain.com
createAccount andy@domain.com password displayName 'Andy Anderson' givenName Andy sn Anderson
createAccount betty@domain.com password displayName 'Betty Brown' givenName Betty sn Brown

Then send the contents of the file to zmprov.

As zimbra:

 zmprov -f commands.zmp

As Root:

 cat commands.zmp | su - zimbra -c zmprov

Useful examples of bulk provisioning with zmprov

You'll probably want to avoid doing a bunch of direct zmprov commands in a bash script if you have a lot to add, since each zmprov command starts up a new jvm for each one. In other words you'll want to avoid doing thousands of these (unless you have plenty of time):

zmprov createDomain domain.com
zmprov  createAccount andy@domain.com password displayName 'Andy Anderson' givenName Andy sn Anderson
zmprov  createAccount betty@domain.com password displayName 'Betty Brown' givenName Betty sn Brown
.. .. ..
.. .. ..

As shown in the first section, you can create a list of subcommands to send to zmprov all at once, which will save time because it's only necessary to start a single jvm. Below are some ways to create a command file from your existing account data.

Passwd File to Zmprov

Following is a perl script to take a passwd file and turn it into a zmprov command file for account provisioning.

=head1 NAME

passwd2zmprov - create zmprov commands from a passwd file


  usage: passwd2zmprov [options] [[passwd_file] ...] > commands.zmp
     -help   show a brief help message
     -man    show the full documentation

     -domain <domain>     [REQUIRED]
     -cosid <cos_id>      [default "Default COS"]
     -password <password> [default ""]

  Getting a COS id:
    zimbra$ zmprov gc <myCos> | grep ^zimbraId:

  Example converting CSV to zmprov commands:
    $ ./passwd2zmprov -domain example.moc /etc/passwd > commands.zmp

  Example provisioning ZCS accounts as 'zimbra' user:
    zimbra$ zmprov -f commands.zmp


Tool to create commands suitable for zmprov from a UNIX passwd file.
We don't use getpwent etc., because we are likely working on a copy
and not running as root.

=head1 HISTORY

 2007/01/23, Version 1.0/1.1 Dlbewley
 2008/03/04, Version 1.2 Plobbes


To execute:

 perl passwd2zmprov -domain example.moc < passwd > mydata.zmp

CSV File to zmprov

Following is a simple perl script to take a CSV file and turn it into the correct zmprov commands

# Lookup the valid COS (Class of Service) ID in the interface or like this
my $cosid = `su - zimbra -c 'zmprov gc Default |grep zimbraId:'`;
$cosid =~ s/zimbraId:\s*|\s*$//g;
while (<>) {
       # CHANGE ME: To the actual fields you use in your CSV file
       my ($email, $password, $first, $last) = split(/\,/, $_, 4);
       my ($uid, $domain) = split(/@/, $email, 2);
       print qq{ca $uid\@$domain $password\n};
       print qq{ma $uid\@$domain zimbraCOSid "$cosid"\n};
       print qq{ma $uid\@$domain givenName "$first"\n};
       print qq{ma $uid\@$domain sn "$last"\n};
       print qq{ma $uid\@$domain cn "$uid"\n};
       print qq{ma $uid\@$domain displayName "$first $last"\n};
       print qq{ma $uid\@$domain zimbraPasswordMustChange TRUE\n};
       print qq{\n};

The above is only a starting place, you will need to change other options (eg: the zimbraPasswordMustChange is an example only) and of course how you create and split the input data.

Also, some CSV files might contain quotes you want to remove.

MacOSX Server mail users

This script will remotely login to your existing MacOSX mail server and retrieve the users from /var/spool/imap/user. You will need an sudo/ssh account on boxes, don't forget to configure the variables at the top of the script

#This file is going to provision all the users for your new Zimbra Mail Server from MacOSX

$hostname1 = "macosx.foo.bar.com";
#Enter the a sudo/SSH username for your new Zimbra server
$username2 = "username";
#Enter the IP/FQDN for your Zimbra server
$hostname2 = "zimbra.foo.bar.com";

LDAP Users to Zimbra Accounts

This script will generate zimbra accounts based on users found in your LDAP server. WARNING: EXISTING ACCOUNTS WILL BE DELETED FROM ZIMBRA, so use with care!


=head1 NAME

ldap2zm  - create zimbra accounts for LDAP users


usage: ldap2zm -h host -b 'base' [ options ]

  -h    LDAP hostname
  -b    LDAP search base

  -v    enable verbose output
  -u    username for LDAP bind
  -p    password for LDAP bind
  -f    LDAP search filter (default: '(objectclass=*)' )
  -l    list users found in LDAP search; take no other action
  -n    new domain (default to first found domain)


ldap2zm will create accounts in zimbra for every user it finds in the specified LDAP server.
Existing accounts are purged from zimbra at the start of each run, so DO NOT RUN THIS ON A 
PRODUCTION ZIMBRA SERVER!  Don't say I didn't warn you. :)

=head1 EXAMPLE

The following command would create zimbra accounts for all employees of example.com who are members of the 
'Zimbra Users' group on the hypothetical Active Directory server 'adserver', using the administrator's 

 ldap2zm -h adserver -u administrator -p s3cr3t -b "DC=example,DC=com" \ 
     -f '(memberOf=CN=Zimbra Users,OU=Employees,DC=example,DC=com)'

This one will also generate email as $user@example.com if email address is missing but it will extract all
regular user from AD (sAMAccountType may differ for you)
 ldap2zm -h adserver -u administrator -p s3cr3t -b "DC=example,DC=com" \ 
     -f "(sAMAccountType=805306368)" -n example.com

Remove Accounts

Here is a script that can be used to remove all accounts and distribution lists, save for accounts you specify. By default it leaves the admin account, the wiki account, and the ham and spam accounts.

# $Id: deprovision,v 1.2 2007/02/18 20:41:43 dlbewley Exp $
# Description:
#   Script to remove all Zimbra accounts and distribution lists.
#   This may be useful for getting back to square one if you are testing bulk 
#   provisioning during a migration.
# See Also:
#   http://wiki.zimbra.com/index.php?title=Bulk_Create
# Usage:
#    su - zimbra
#    ./deprovision > deprovision.zmp
#    zmprov < deprovision.zmp

# this will be passed to grep -vE which acts as an exclude list
# this will be passed to grep -vE which acts as an exclude list
# files to hold distlist and account lists


# get accounts lists
zmprov gaa > "$TMPA"
if [ -n "$KEEP_ACCOUNTS" ]; then
    grep -vE "$KEEP_ACCOUNTS" "$TMPA" > "$ACCOUNTS"
    rm "$TMPA"

# get distribution lists
zmprov gadl > "$TMPL"
if [ -n "$KEEP_LISTS" ]; then
    grep -vE "$KEEP_LISTS" "$TMPL" > "$LISTS"
    rm "$TMPL"
