Hi,
I am getting following exception while i am doing search using spring-ldap.

org.springframework.ldap.UncategorizedLdapException: Uncategorized exception occured during LDAP processing; nested exception is javax.naming.NamingException: [LDAP: error code 80 - internal error]; remaining name ''
Caused by:

I don't see any reason for this as everything was working fine and suddenly this exception came.
Can you tell me any reason for this?
