LDAP errror in dialup admin page

[Bishal]

I am trying to use freeradius 1.1.7 in Freebsd 6.2 with openldap 2.3.37
for authentication and mysql for accounting.

While creating new user I get following error in dialup admin page:

Warning: file(/usr/local/etc/raddb/ldap.attrmap) [function.file]: failed
to open stream: Permission denied in
/usr/local/www/apache22/data/dialupadmin/lib/ldap/attrmap.php3 on line 4

Warning: Invalid argument supplied for foreach() in
