35 * Glossary:
36 *
37 * GROUP a group object (an entry with GROUP_OC
38 * objectClass)
39 * MEMBER a member object (an entry whose DN is
40 * listed as MEMBER_AT value of a GROUP)
41 * GROUP_OC the objectClass of the group object
42 * (default: groupOfNames)
43 * MEMBER_AT the membership attribute, DN-valued;
44 * note: nameAndOptionalUID is tolerated
45 * as soon as the optionalUID is absent
46 * (default: member)
47 * MEMBER_OF reverse membership attribute
48 * (default: memberOf)
49 *
50 * - add:
51 * - if the entry that is being added is a GROUP,
52 * the MEMBER_AT defined as values of the add operation
53 * get the MEMBER_OF value directly from the request.
54 *
55 * if configured to do so, the MEMBER objects do not exist,
56 * and no relax control is issued, either:
57 * - fail
58 * - drop non-existing members
59 * (by default: don't muck with values)
60 *
61 * - if (configured to do so,) the referenced GROUP exists,
62 * the relax control is set and the user has
63 * "manage" privileges, allow to add MEMBER_OF values to
64 * generic entries.
65 *
66 * - modify:
67 * - if the entry being modified is a GROUP_OC and the
68 * MEMBER_AT attribute is modified, the MEMBER_OF value
69 * of the (existing) MEMBER_AT entries that are affected
70 * is modified according to the request:
71 * - if a MEMBER is removed from the group,
72 * delete the corresponding MEMBER_OF
73 * - if a MEMBER is added to a group,
74 * add the corresponding MEMBER_OF
75 *
76 * We need to determine, from the database, if it is
77 * a GROUP_OC, and we need to check, from the
78 * modification list, if the MEMBER_AT attribute is being
79 * affected, and what MEMBER_AT values are affected.
80 *
81 * if configured to do so, the entries corresponding to
82 * the MEMBER_AT values do not exist, and no relax control
83 * is issued, either:
84 * - fail
85 * - drop non-existing members
86 * (by default: don't muck with values)
87 *
88 * - if configured to do so, the referenced GROUP exists,
89 * (the relax control is set) and the user has
90 * "manage" privileges, allow to add MEMBER_OF values to
91 * generic entries; the change is NOT automatically reflected
92 * in the MEMBER attribute of the GROUP referenced
93 * by the value of MEMBER_OF; a separate modification,
94 * with or without relax control, needs to be performed.
95 *
96 * - modrdn:
97 * - if the entry being renamed is a GROUP, the MEMBER_OF
98 * value of the (existing) MEMBER objects is modified
99 * accordingly based on the newDN of the GROUP.
100 *
101 * We need to determine, from the database, if it is
102 * a GROUP; the list of MEMBER objects is obtained from
103 * the database.
104 *
105 * Non-existing MEMBER objects are ignored, since the
106 * MEMBER_AT is not being addressed by the operation.
107 *
108 * - if the entry being renamed has the MEMBER_OF attribute,
109 * the corresponding MEMBER value must be modified in the
110 * respective group entries.
111 *
112 *
113 * - delete:
114 * - if the entry being deleted is a GROUP, the (existing)
115 * MEMBER objects are modified accordingly; a copy of the
116 * values of the MEMBER_AT is saved and, if the delete
117 * succeeds, the MEMBER_OF value of the (existing) MEMBER
118 * objects is deleted.
119 *
120 * We need to determine, from the database, if it is
121 * a GROUP.
122 *
123 * Non-existing MEMBER objects are ignored, since the entry
124 * is being deleted.
125 *
126 * - if the entry being deleted has the MEMBER_OF attribute,
127 * the corresponding value of the MEMBER_AT must be deleted
128 * from the respective GROUP entries.
