So the rdn is relative to its parent. And the canonicalname cn is just an attribute. Sometimes the cn and the rdn have the same value. Other times, the rdn is uid=user (instead of cn=user), like most unix ldap servers do. So the dn would then be uid=user,ou=users,dc=domain,dc=tld.

How to transfer a DN in LDAP?
Whenever a DN needs to be transferred in LDAP, that is generally done using its string representation. The string representation of a DN is simply the string representations of each of its RDNs, with each RDN separated by a comma. Usually, an RDN consists of an attribute type name (never including attribute options) followed by an equal sign and the string representation of the corresponding attribute value, with the plus sign used to separate the name-value pairs in a multivalued RDN. However, there are special cases in which it is necessary to escape one or more characters in an RDN. Some of those cases include:
How many name value pairs are there in a RDN?
Each RDN is comprised of name-value pairs. Every RDN must contain at least one pair (an attribute name followed by an equal sign and the value for that attribute), but you can include multiple name-value pairs in the same RDN by separating them with plus signs.
What is a distinguished name?
A distinguished name (usually just shortened to “DN”) uniquely identifies an entry and describes its position in the DIT. A DN is much like an absolute path on a filesystem, except whereas filesystem paths usually start with the root of the filesystem and descend the tree from left to right, LDAP DNs ascend the tree from left to right. For example, the DN “uid=john.doe,ou=People,dc=example,dc=com” represents an entry that is immediately subordinate to “ou=People,dc=example,dc=com” which is itself immediately subordinate to the entry “dc=example,dc=com”.
What is a null DN?
This DN, whose string representation doesn’t have any characters, is often called the zero-length DN or the null DN. The null DN may be used to reference a special entry called the root DSE, which provides a lot of useful information about the directory server (e.g., the features supported by that server, the server software version, etc.). The root DSE will be described in more detail elsewhere.
Can LDAP have multiple strings?
LDAP DNs may actually have multiple string representations. You can have any number of spaces around the commas separating RDN components. You can have any number of spaces around the equal signs separating RDN attributes from their values. You can have any number of spaces around the plus signs separating the elements of a multivalued RDN. The attributes in a multivalued RDN may appear in any order. You can use any kind of capitalization for attribute names. You can use the OID to reference an attribute instead of the attribute name, and some attributes may have multiple names. There may be multiple ways of representing some or all of the values of the RDN components (e.g., differences in capitalization may be considered insignificant). For example, all of the following are valid ways of representing the same DN:
Is a DN an RDN?
Note that even though each component of a DN is in itself an RDN, it is a common practice to refer to the leftmost component of an entry’s DN as the RDN for that entry, and to refer to the attributes included in that RDN component as naming attributes.
Is a DN required for LDAP?
It’s also worth pointing out that there is no requirement for the topmost entry in an LDAP tree to contain a single component. For example, it is entirely legal for a directory server to be configured such that it has an entry with DN “dc=example,dc=com” but not an entry with DN “dc=com”. The DN of the entry that is at the top of an LDAP tree is called a naming context (or sometimes referred to as a suffix).
Question
Could you please tell me the difference between canonical name and distinguished name. Please use easy English and example. thanks
All replies
Distinguished Name is a name or value / attribute of the object that uniquely identifies it in Active Directory. For example User1 and User2 both are active directory objects in my domain xyz.local. Canonical name is another notation to define the AD Object in a different format without (OU= or CU=) as shown below:
