Structures LDAP Distinguished Name strings into a visualized tree.
For example, providing a slice of strings like
"CN=SPSAdmins,OU=Groups,OU=MYTOWN,OU=Germany,OU=MYCOMPANY,DC=MYTOWN,DC=MYCOMPANY,DC=com",
"CN=FooAdmin,OU=Groups,OU=MYTOWN,OU=Germany,OU=MYCOMPANY,DC=MYTOWN,DC=MYCOMPANY,DC=com",
"CN=BarAdmin,OU=Groups,OU=MYTOWN,OU=Germany,OU=MYCOMPANY,DC=MYTOWN,DC=MYCOMPANY,DC=com",
"CN=SPSAdmins,OU=Groups,OU=MYTOWN,OU=America,OU=MYCOMPANY,DC=MYTOWN,DC=MYCOMPANY,DC=com",
"CN=FooAdmin,OU=Groups,OU=MYTOWN,OU=America,OU=MYCOMPANY,DC=MYTOWN,DC=MYCOMPANY,DC=com",
"CN=BarAdmin,OU=Groups,OU=MYTOWN,OU=America,OU=MYCOMPANY,DC=MYTOWN,DC=MYCOMPANY,DC=com",
"CN=SPSAdmins,OU=Groups,OU=YourTown,OU=America,OU=MYCOMPANY,DC=MYTOWN,DC=MYCOMPANY,DC=com",
"CN=FooAdmin,OU=Groups,OU=YourTown,OU=America,OU=MYCOMPANY,DC=MYTOWN,DC=MYCOMPANY,DC=com",
"CN=BarAdmin,OU=Groups,OU=YourTown,OU=America,OU=MYCOMPANY,DC=MYTOWN,DC=MYCOMPANY,DC=com",
"CN=LongAdmin,OU=Bob,OU=Doug,OU=gone,OU=Groups,OU=YourTown,OU=America,OU=MYCOMPANY,DC=MYTOWN,DC=MYCOMPANY,DC=com",
"CN=ShortAdmin,OU=Groups,OU=MYCOMPANY,DC=MYTOWN,DC=MYCOMPANY,DC=com",
You would get

TYPES
type Node struct {
Value string `json:"label"`
Class string `json:"class"`
Children []*Node `json:"children,omitempty"`
Parent *Node `json:"-"`
ParentUid string `json:"parentUid"`
Uid uuid.UUID `json:"uid"`
Depth int `json:"depth"`
Lineage string `json:"lineage"`
}
Node contains properties and methods to represent an object in the LDAP tree
and to alter properties such as children, parent, value, etc.
func BuildTree(input []string) (root *Node, vis string, err error)
BuildTree takes a slice of LDAP Distinguished Name strings and attempts to
build a node tree that represents all of their relationships (if any) under
a generic parent "root" node.
It will return the root node object and the visualization string and any
errors.
func (n *Node) AddChild(child *Node)
AddChild adds a Node to this node's children and updates the provided Node's
parent property as well.
func (n *Node) AddParent(parent *Node)
AddParent updates the parent of the current node to the node provided in the
argument. Somewhat safe.
func (n *Node) FmtTree(start string) string
FmtTree returns a string formatted as a multiline tree representing thise
Node and it's children.
func (n *Node) HasChild(value string) (found bool)
HasChild searches the Node's children for a child with the requested value.
