LDAP_SEARCH Business Interlink Definition: Execution failed.

Hi Experts,

Though we are using custom Application Engine process to sync emails from Active Directory into PeopleSoft, we used PS delivered Business Interlink LDAP_SEARCH. Process working fine since more than 2 years. We got error "Interlink Definition: Execution failed. (122,2)". Error line pointing to

&EXECRSLT = &LDAP_SEARCH_1.Execute(); where &LDAP_SEARCH_1 = GetInterlink(Interlink.LDAP_SEARCH);

I'm seeing this error for first time on our end.

Looks like something wrong while executing Interlink LDAP_SEARCH. When checked in PIA Test connections look fine.

Any pointers would be appreciated!

Thanks.
