LDAP Search attribute with multiple occurence

Question

i am looking for a ldap filter to find users who have an multi value attribute with duplicate values.

For example in this case i will find the users with duplicate {PersNumber}:

MVAttribute {PersNumber}111111 {PersNumber}111112

I tried many filters, but i could not find the right one yet.

It is not an ldap search solution, but depeding on the number of users you could export the users in EXPORT.ldif and then apply an ldif awk solution in [https://stackoverflow.com/questions/74649357/remove-duplicate-attributes-for-a-core-single-value-no-user-modification-attri/75235694#75235694]. Hier is the modified awk script for duplicate Attribute cn

grep '^dn:\|^cn:' REPORT.ldif | awk
'BEGINN {L1="",L2="";TYP="";DN_PREF="dn:";DN=""}
{ 
  if (TYP==$1 && L2==$2) {
    printf("\n%s %s\n%s %s\n%s %s\n--------",
      DN_PREF,DN,
      $1,$2,
      L1,L2);
  }
  if (TYP==$1) {
    DN=$2;
  }
  L1=$1;
  L2=$2;
}'
