static means it has all of the external libraries "internal" - so it never has to worry about library versions being correct. These image files are huge and use a lot of memory. Image activation takes longer and uses more resources than shared, especially in the event that the file is called inside a shell script loop, for example. Deployment of these is usually a slam-dunk

shared means it has all of the external libraries "external" - so it always has to worry about library versions being correct and opening them. These image files are small and use relatively smaller memory allocations. They load faster. Deployment can be iffy, so installation requires a full check of the versions of externale libraries.

There is advantage to dynamic, in that it allows you to specify exactly which versions of libraries to open, if you chose to do that. This also allows you to override LD_LIBRARY_PATH settings.

slapo-dyngroup

SLAPO-DYNGROUP(5)						File Formats Manual						 SLAPO-DYNGROUP(5)

NAME

       slapo-dyngroup - Dynamic Group overlay to slapd

SYNOPSIS

       /etc/openldap/slapd.conf

DESCRIPTION

       The  Dynamic  Group overlay allows clients to use LDAP Compare operations to test the membership of a dynamic group the same way they would
       check against a static group. Compare operations targeting a group's static member attribute will be intercepted  and  tested  against  the
       configured dynamic group's URL attribute.

       Note  that  this  intercept only happens if the actual Compare operation does not return a LDAP_COMPARE_TRUE result. So if a group has both
       static and dynamic members, the static member list will be checked first.

CONFIGURATION

       This slapd.conf option applies to the Dynamic Group overlay.  It should appear after the overlay directive.

       attrpair <memberAttr> <URLattr>
	      Specify the attributes to be compared. A compare operation on the memberAttr will cause the URLattr to be evaluated for the result.

EXAMPLES

	 database bdb
	 ...
	 overlay dyngroup
	 attrpair member memberURL

FILES

       /etc/openldap/slapd.conf
	      default slapd configuration file

SEE ALSO

       slapd.conf(5), slapd-config(5).
