Whenever I'm stuck with figuring out proper LDAP usage, I revert to testing with LDAP Browser Editor Despite. Based on your code looking for sAMAccountname, plus the fact you call your variable 'ad', I'm guessing you're hitting an Active Directory server. I know that LBE will be able to hit it (it works with ours) and you can triple check your filters.

For one thing, you need parens around the filter: (dn=CN=JUSER,OU=ACCT,DC=MYCOMPANY,DC=COM). I always use dn, but distinguishedname might also be valid. Use the sAMAccountname filter to view your entry in LBE and verify that you are actually using the distinguished name of the person

    There were two issues. First, I had to use distinguishedname= rather than dn=a. Apparently Active Directory is picky about the filter though oddly you can use dn when specifying get_value. Secondly, the sample distinguishednames I tested had parens in them which must be escaped. Net::LDAP doesn't handle that for you.

    I added this bit:

    sub cleanLDAPString { my $tempstr = shift; $tempstr =~ s/\\/\\5c/; $tempstr =~ s/\(/\\28/; $tempstr =~ s/\)/\\29/; $tempstr =~ s/&/\\26/; $tempstr =~ s/\|/\\7c/; $tempstr =~ s/>/\\3e/; $tempstr =~ s/</\\3c/; $tempstr =~ s/\~/\\7e/; $tempstr =~ s/\*/\\2a/; return $tempstr; }

    and called it before I constructed the filter. Worked just fine. Thank you very much for the feedback. It helped lead me to the solution.


    And nuts to those that think minimalist responses and snide comments are in any way helpful to the people who come here. If you don't have anything helpful to contribute then don't post. And for the record, posting greps to the doc that I already specified I'd read and that didn't have any relevant examples is just effing arrogant and lazy.

      The idiom of that function is

      { my %subs = ( '\\' => q/\\5c/, '(' => q/\\28/, ')' => q/\\29/, '&' => q/\\26/, '|' => q/\\7c/, '>' => q/\\3e/, '<' => q/\\3c/, '~' => q/\\7e/, '*' => q/\\2a/, ); my $subs_re = join '|', map quotemeta, key %subs; sub cleanLDAPString { my $tempstr = shift; $tempstr =~ s/($subs_re)/$subs{$1}/g; return $tempstr; } }

      But it already exists in Net::LDAP::Util

      escape_filter_value ( VALUES )
      unescape_filter_value ( VALUES )
      escape_dn_value ( VALUES )
      unescape_dn_value ( VALUES )
