Use this script for set automatic Default Signatures for all users reading it's LDAP information.

I asume that user have any information in his LDAP attributes.

The script set_signature.sh:

  #!/bin/bash
  
  RUTA="/opt/zimbra/bin"
  
  # Check for run as zimbra user
  ID=`id -u -n`
  if [ x$ID != "xzimbra" ]; then
     echo "Please run as ZIMBRA user"
     echo "Exiting..."
     exit 1
  fi
  
  
  # Obtain all accounts
  accounts=`$RUTA/zmprov -l gaa`
  
  for ac in $accounts; do
     echo -ne "Checking account: $ac \t"
  
     # Verify for set signature
     sign=`$RUTA/zmprov -l ga $ac | grep zimbraPrefMailSignatureEnabled | cut -d : -f 2`
  
     if [ `echo $sign | grep TRUE` ]; then
        echo "This account have a Signature. Nothing to do."
     else
        echo -ne "Setting signature... "
  
        # Obtain signature from LDAP user atributes
        signature=`$RUTA/zmprov ga $ac | egrep "(^cn|^ou|^company|^street|^telephoneNumber)" | cut -d : -f 2 | sed 's/^\ //g'`
  
        # Set signature for account $ca
        $RUTA/zmprov ma $ac zimbraPrefMailSignatureEnabled TRUE  zimbraPrefMailSignatureStyle internet zimbraPrefMailSignature "$signature"
  
        echo "done!"
     fi
  
  done

For example: My LDAP user is:

  # name daniel@test.cl
  cn: Daniel A. Eugenin
  co: Chile
  company: IT Linux Ltda.
  displayName: Daniel A. Eugenin
  givenName: Daniel
  initials: A
  l: Santiago
  objectClass: organizationalPerson
  objectClass: zimbraAccount
  objectClass: amavisAccount
  ou: Informatica
  postalCode: 00000
  sn: Eugenin
  street: General Holley XXX of. XX - Providencia
  telephoneNumber: (+56-2) XXX XX XX
  uid: daniel
  ...

And the signature result:

  -- 
  Daniel A. Eugenín
  IT Linux Ltda.
  Informática
  General Holley XXX of. XX - Providencia
  (+56-2) XXX XX XX
