OpenDJ Administration Guide
Chapter 5. Configuring Privileges & Access Control

Once you set up a number of ACIs, you might find it difficult to understand by inspection what rights a user actually has to a given entry. The Get Effective Rights control can help.

	Note
	The control OID, 1.3.6.1.4.1.42.2.27.9.5.2, is not allowed by the default global ACIs.

In this example, Babs Jensen is the owner of a small group of people who are willing to carpool.

$ ldapsearch
 --port 1389
 --bindDN "uid=bjensen,ou=people,dc=example,dc=com"
 --bindPassword hifalutin
 --baseDN "ou=Self Service,ou=Groups,dc=example,dc=com"
 "cn=*" 
dn: cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com
objectClass: groupOfNames
objectClass: top
member: uid=bjensen,ou=People,dc=example,dc=com
description: People who are willing to carpool
owner: uid=bjensen,ou=People,dc=example,dc=com
cn: Carpoolers

Performing the same search with the get effective rights control, and asking for the aclRights attribute, shows what rights Babs has on the entry.

$ ldapsearch
 --control effectiverights
 --port 1389
 --bindDN "uid=bjensen,ou=people,dc=example,dc=com"
 --bindPassword hifalutin
 --baseDN "ou=Self Service,ou=Groups,dc=example,dc=com"
 "cn=*"
 aclRights
dn: cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com
aclRights;entryLevel: add:0,delete:1,read:1,write:0,proxy:0

Requesting the aclRightsInfo attribute results in information about the ACIs applied to arrive at the results.

$ ldapsearch
 --control effectiverights
 --port 1389
 --bindDN "uid=bjensen,ou=people,dc=example,dc=com"
 --bindPassword hifalutin
 --baseDN "ou=Self Service,ou=Groups,dc=example,dc=com"
 "cn=*"

aclRightsInfo;logs;entryLevel;add: acl_summary(main): access not allowed(add) on

aclRightsInfo;logs;entryLevel;delete: acl_summary(main): access allowed(delete)

You can also request the effective rights for another user by using the --getEffectiveRightsAuthzid (short form: -g) option, which takes the authorization identity of the other user as an argument. The following example shows Directory Manager checking anonymous user rights to the same entry. Notice that the authorization identity for an anonymous user is expressed as "dn:".

$ ldapsearch
 --getEffectiveRightsAuthzid "dn:"
 --port 1389
 --bindDN "cn=Directory Manager"
 --bindPassword password
 --baseDN "ou=Self Service,ou=groups,dc=example,dc=com"
 "cn=*" aclRightsInfo
dn: cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com
aclRightsInfo;logs;entryLevel;read: acl_summary(main): access allowed(read) on e
 ntry/attr(cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com, objectClas
 s) to (anonymous) (not proxied) ( reason: evaluated allow , deciding_aci: Anony
 mous read-search access)
aclRightsInfo;logs;entryLevel;write: acl_summary(main): access not allowed(write
 ) on entry/attr(cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com, NULL
 ) to (anonymous) (not proxied) ( reason: no acis matched the subject )
aclRightsInfo;logs;entryLevel;add: acl_summary(main): access not allowed(add) on
  entry/attr(cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com, NULL) to
  (anonymous) (not proxied) ( reason: no acis matched the subject )
aclRightsInfo;logs;entryLevel;delete: acl_summary(main): access not allowed(dele
 te) on entry/attr(cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com, NU
 LL) to (anonymous) (not proxied) ( reason: no acis matched the subject )
aclRightsInfo;logs;entryLevel;proxy: acl_summary(main): access not allowed(proxy
 ) on entry/attr(cn=Carpoolers,ou=Self Service,ou=Groups,dc=example,dc=com, NULL
 ) to (anonymous) (not proxied) ( reason: no acis matched the subject )

When you need to check access to an attribute that might not yet exist on the entry, you can further use the --getEffectiveRightsAttribute (short form: -e) option, which takes an attribute list as an argument. The following example shows Directory Manager checking anonymous user access to the description attribute for the Self Service groups organizational unit entry. The description attribute is not present on the entry, yet.

$ ldapsearch
 --port 1389
 --baseDN "ou=Self Service,ou=groups,dc=example,dc=com"
 "ou=Self Service" description
dn: ou=Self Service,ou=Groups,dc=example,dc=com

$ ldapsearch
 --getEffectiveRightsAuthzid "dn:"
 --getEffectiveRightsAttribute description
 --port 1389
 --bindDN "cn=Directory Manager"
 --bindPassword password
 --baseDN "ou=Self Service,ou=groups,dc=example,dc=com"
 "ou=Self Service" aclRights
dn: ou=Self Service,ou=Groups,dc=example,dc=com
aclRights;attributeLevel;description: search:1,read:1,compare:1,write:0,selfwrit
