Dear Expert,<br>                    I am currently using unique overlay with uid and mail attributes which is working perfectly for me but now i want to make it unique across the directory like if i am using mailAlternateAddress attribute and try to add any value which is already defined in mail attribute should not be allowed.<br>
<br>Example -- mail: <a href="mailto:piyush@xxx.com">piyush@xxx.com</a> is already there in ldap dit  then <a href="mailto:piyush@xxx.com">piyush@xxx.com</a> should not be allowed in mailAlternateAddress attribute&#39;s value and vice versa. <br>
<br>Any help would be appreciated !!!<br><br>OpenLDAP version - 2.4.19<br>BDB version - 4.7.25 <br clear="all"><br>-- <br>Regards <br><br>******************************<br>Piyush Joshi<br>System administrator<br>9415414376<br>
