Zimbra automation using scripting.


How to change users's individual signatures based on their ldap attributes globally


Purpose

The purpose of this article is to show how to create a simple script which, can modify every user's signature globally, based on their ldap attribute values in ldap.

Resolution

For the purpose we will use two scripts. In the process I will explain why combining the two scripts into one will not work.

Script 1

#!/bin/bash
  
path="/opt/zimbra/bin"
  
     for i in `/opt/zimbra/bin/zmprov -l gaa`  
      do
       echo -ne "Checking account: $i \t"
       
       $path/zmprov ma $i zimbraPrefMailSignatureEnabled TRUE
       signature=`$path/zmprov ga $i | egrep "(^cn|^ou|^company|^street|^telephoneNumber|^mobile|^title)" | cut -d : -f 2 | sed 's/^\ //g'`
       $path/zmprov ma $i zimbraPrefMailSignature "$signature"
       echo "done!"

    done
  • The first script does the following:
set the default path to zmprov.
sets the zimbraPrefMailSignatureEnabled attribute to TRUE.
sets a variable called signature.
assigns to this variable different attribute values, that are assign to that user in LDAP. In this example: (^cn|^ou|^company|^street|^telephoneNumber|^mobile|^title). The attributes can be changed as per the admin needs.
the last line modifies the account, as it writes the values from LDAP to the signature of the user.

Script 2

#!/bin/bash

path="/opt/zimbra/bin"
  
    for i in `/opt/zimbra/bin/zmprov -l gaa`  
     do
       echo -ne "Adding SignatureID to account: $i \t"

       signatureid=`$path/zmprov ga $i zimbraSignatureId | sed -n '2p' | cut -d : -f 2 | sed 's/^\ //g'`
       $path/zmprov ma $i zimbraPrefDefaultSignatureId "$signatureid"
       $path/zmprov ma $i zimbraPrefForwardReplySignatureId "$signatureid"
       echo "done!"
     done


  • The second script:
assigns a value to the zimbraSignatureId attribute.
assigns the value from zimbraSignatureId, to the zimbraPrefDefaultSignatureId attribute.
assigns the value from zimbraSignatureId, to the zimbraPrefForwardReplySignatureId attribute.
