ldap client in Solaris 10

Hi,

We set up Solaris ldap client as the opendj server.

Recently, we've found the "logins" or "getent passwd" return infinite loop of ldap users who can access the server.

For instances, if two ldap users smith and jason who can access to the server, "getent passwd" will return as

....

smith:x:123:456: xxxxx:/home/smith:/bin/ksh

jason:x124:456:xxxxx:/home/jason:/bin/ksh

smith:x:123:456: xxxxx:/home/smith:/bin/ksh

jason:x124:456:xxxxx:/home/jason:/bin/ksh

smith:x:123:456: xxxxx:/home/smith:/bin/ksh

jason:x124:456:xxxxx:/home/jason:/bin/ksh

.......

it will keep returning forever.

Your help is most appreciated.
