RootDSE stands for Root DSA (Directory Service Agent) Specific Entry, which is the root of the LDAP server. This entry is a pseudo object in the tree, which means it's an unnamed entry at the root of the tree. This entry holds the configuration information about the connected eDirectory server. As mentioned, the rootDSE is an unnamed entry, a search against the eDirectory tree won't return you the rootDSE object.
The following is list contains the most common information that a rootDSE holds.
All the above information can be read by doing a simple LDAP search against the RootDSE object using the following settings:
This can be done through the ldapsearch tool or even through a simple application written using any LDAP SDK.
So, the ldapsearch to do the RootDSE search would look like:
ldapsearch -h <hostname> -p <port number> -b "" -s base "objectclass=*"
The following is the sample output of the RootDSE search:
