There are three servers/daemon in OID:

OIDLDAPD – This is the main server/daemon WAITING for ldap request (ldapsearch, ldapadd, ldapmodify, ldapdelete..). When any APPLICATION want to do any ldap operation(add, modify, delete, search..) on OID object (USER, group, application..), that request is fulfilled by this server/daemon.

ODISRV – also CALLED as Oracle Directory Integration Server, this is used for integration of Various Application (Portal, BI, E-Business Suite/Apps) with OID for user/group data. If any user/group is added/deleted in Portal/BI synchronization of that user to OID is done by this Daemon (Vice Versa). If you have Integrated Apps(11i/R12) with OID/SSO then users is provisioned/de-provisioned using this daemon of OID.

OIDREPLD – Also called as OID Replication Daemon is used if you have replicated OID. By default this daemon is disabled.
