Zmprov Command Files

The Zmprov command will accept commands from a file. Just pass the commands in on standard input like this.

As Zimbra:

 zmprov < commands.zmp

As Root:

 cat commands.zmp | su - zimbra -c zmprov

Below are some ways to create a command file from your existing account data.

Create Accounts

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.

#!/usr/bin/perl
################################################################################
# $Id: passwd2zmprov,v 1.1.1.1 2007/01/23 18:04:38 dlbewley Exp $
#-------------------------------------------------------------------------------
# Description:
#   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.
#
# See Also:
#   http://wiki.zimbra.com/index.php?title=Bulk_Create
#
# Usage:
#    ./passwd2zmprov /etc/passwd > users.zmp
#    zmprov < users.zmp
################################################################################

my $DOMAIN='hostname.foo.bar'; # zimbra installation domain name
my $MIN_UID=500;  # skip system accounts like httpd
my $MAX_UID=5000; # skip other system accounts like nfsnobody
my $PASSWORD='password'; # default password
# Zimbra Class Of Service for users
my $COS_ID = 'e00000a0-0c00-00d0-000a-000d00afea0a'; # use during testing only
#my $COS_ID = `su - zimbra -c 'zmprov gc Default |grep zimbraId:'`;
#$COS_ID =~ s/zimbraId:\s*|\s*$//g;


while(<>) {
    chomp;
    my ($uname,$x,$uid,$gid,$gecos,$dir,$shell) = split(/:/);
    if (! ($MIN_UID < $uid && $uid < $MAX_UID)) {
        warn "skipping $uname, $uid not between $MIN_UID and $MAX_UID";
        next;
    }

    my $date = localtime(time);
    my ($fullname,$description) = split(/\s*,\s*/,$gecos,2);
    my ($fname,$initial,$lname) = split(/\s+/,$fullname);
    if (! $lname) {
        $lname = $initial;
        undef $initial;
    }
    my $displayname = "$fname $initial $lname";
    $displayname =~ s/\s+/ /;

    print qq{ca $uname\@$DOMAIN "$PASSWORD"\n};
    print qq{ma $uname\@$DOMAIN zimbraCOSid "$COS_ID"\n};
    print qq{ma $uname\@$DOMAIN givenName "$fname"\n};
    print qq{ma $uname\@$DOMAIN sn "$lname"\n};
    print qq{ma $uname\@$DOMAIN cn "$uname"\n};
    print qq{ma $uname\@$DOMAIN displayName "$displayname"\n};
    print qq{ma $uname\@$DOMAIN description "$description"\n};
    print qq{ma $uname\@$DOMAIN zimbraNotes "Migrated $date"\n};
    print qq{ma $uname\@$DOMAIN zimbraPasswordMustChange TRUE\n};
    print qq{\n};
}

To execute:

 perl passwd2zmprov < 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

#!/usr/bin/perl
 
# 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 (<>) {
       chomp;
 
       # 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 may contain quotes you want to remove.


Create Aliases

Aliases File to Zmprov
