LDAP servers can be configured to use as authenticator in Weblogic Server. In order to efficiently use an LDAP server, it must be possible to uniquely identify LDAP objects. GUID attributes can be considered a unique identifier for an LDAP object. There are several specific and some more generic LDAP authentication providers available for Weblogic Server. The specific authentication providers have default GUID (global universal identifier) attributes (see here at 'Use of GUID and LDAP DN Data in WebLogic Principals'). When using the generic Weblogic Server LDAPAuthenticator, there is no default GUID attribute. In order for LDAP caching to work and to allow browsing of group memberships for users, the GUID attribute needs to be defined. The entryUUID is a good candidate for this since every LDAP server should support it. See RFC 4530. Also see here.

Continuous Delivery is something a lot of companies strife for. It is a software development practice which allows quick (continuous) delivery of software. Quick delivery means the software can quickly provide business value. Why is it difficult to achieve and what are the challenges which need to be faced? Inspired by a Continuous Delivery conference in the Netherlands and personal experiences, some personal thoughts on the subject. The bottom line is that it requires a cultural change in a company and it is a joint effort of several departments/disciplines to make it work. The below image is taken from here. The Continuous Delivery maturity model is an interesting read to understand what Continuous Delivery is and provides a way to measure where you are as a company.
