Is there a way to display the text representation of an ldap 
search-filter using tshark?

I tried -e ldap.filter but this is only a 32 bit filter element (only 
the first filter element). Is there another display filter or a 
function that displays a human readable version of the whole 
search-filter?

The source code has a list of possible values for the ldap.filter 
number:

  { 0, "and" },
  { 1, "or" },
  { 2, "not" },
  { 3, "equalityMatch" },
  { 4, "substrings" },
  { 5, "greaterOrEqual" },
  { 6, "lessOrEqual" },
  { 7, "present" },
  { 8, "approxMatch" },
  { 9, "extensibleMatch" },

Are these values you're trying to display?  I don't think it's possible 
in tshark right now, although I thought I saw a request for that and 
possibly even work toward it not too long ago.  Wireshark displays 
those text strings in the custom columns now.

Actually I was trying to display a string representation of the whole
search filter, not just the initial "search operator".

Something like the line that the "tshark -V" output displays for an ldap
search filter:

           Filter: (&(objectclass=wuDepartment)(departmentNumber=3789))
