Hello Christian,

I don't know the exact syntax for ldapsearch because I haven't used it 
for ages.

filter => '*' indeed is no valid filter.  It is a bit like trying an SQL 
command like SELECT contextCSN FROM $table WHERE *

If I remember correctly, you either need to omit the filter:

$search = $ldap->search(
     base   => $BaseDn,
     scope  => 'base',
     attrs  => [ 'contextCSN'],
);

or set on which attribute you search for:

$search = $ldap->search(
     base   => $BaseDn,
     scope  => 'base',
     filter => '(contextCSN=*)',
     attrs  => [ 'contextCSN'],
);

Also see the examples for search in 
https://metacpan.org/pod/distribution/perl-ldap/lib/Net/LDAP.pod and for 
the syntax 
https://metacpan.org/pod/distribution/perl-ldap/lib/Net/LDAP/Filter.pod

BTW: it's better to copy&paste code, because the code you gave in your 
call for help will never compile, see the red annotations in your code 
example.

Kind regards

Strat

could need some help.

I want to do with Net::LDAP what ldapsearch is doing with:
ldapsearch -x -LLL -s base contextCSN

with Net::LDAP I am struggeling ... tried the following:

$search = <font color="#ff0000">ldap</font>-&gt;search( base =&gt; $BaseDn, scope =&gt; <font color="#ff0000">''base'</font>, filter =&gt;
'*', attrs =&gt; <font color="#ff0000">'contextCSN']</font> );

This results in Bad filter.
From man page of ldapsearch there is no filter defined ... so is this
possible with Net::LDAP ?

Thank you
