Hi Perl Monks,

I have been working with LDAP server configurations from some time and now I want to integrate the LDAP in my project.

I want to use LDAP to authenticate the users when they login to my portal.

I found Net::LDAP as a good perl module that can be used to serve my purpose.

I was successful in executing search statements and here is the code

#! /usr/bin/perl use Net::LDAP; $ldap = Net::LDAP->new ( "<ip address>" ) or die "Connection Failed $@ +"; $mesg = $ldap->bind ( "<user name>", password => "<password>", version => 3 ); $base = "dc=example,dc=com"; $mesg = $ldap->search ( # perform a search base => $base, filter => "(objectclass=*)" ); $mesg->code && die $mesg->error; foreach $entry ($mesg->all_entries) { $entry->dump; }
for the above code I got the following correct output:
--------------------------------------------------------------------- +--- dn:dc=example,dc=com dc: example description: Root LDAP entry for objectClass: dcObject organizationalUnit ou: rootobject ---------------------------------------------------------------------- +-- dn:ou=People,dc=example,dc=com ou: People description: All people in organisation objectClass: organizationalUnit ---------------------------------------------------------------------- +-- dn:uid=srinivas,ou=People,dc=example,dc=com uid: srinivas cn: srinivas objectClass: account posixAccount top shadowAccount userPassword: {crypt}$1$zYwJ/asE$DsYRb6CXjzJihNyTV2lC9. shadowLastChange: 13986 shadowMax: 99999 shadowWarning: 7 loginShell: /bin/bash uidNumber: 503 gidNumber: 100 homeDirectory: /home/srinivas
now when I am trying to execute compare function whose code is
$mesg = $ldap->compare( $base, attr => "uid", value => "srinivas" ); $mesg->code && die $mesg->error; foreach $entry ($mesg->all_entries) { $entry->dump; }
I am getting following error when I execute the above script
No such attribute at line 34, <DATA> line 259.
Can any one suggest whether there are any additional attributed that are to be added or any other why that I can compare my username and password for authentication. Any suggestion will be helpful.

Thanks in Advance.
