MIIS/ILM Code Experiment: Generic AD/ADAM Provisioning Function
Here is a fairly simple function to provision a user in Active Directory or ADAM and can be used interchangably so long as ADAM uses the object class "user"
This function is making the assumption that your design will determine the RDN, the LDAP container/OU that the object will sit and the string name of the management agent you are provisioning to.
/*
* ProvisionLDAPUser - Generic Provisioning function
* mventry is the affected metaverse entry
* MAName is the name of the Destination Management Agent
* rdn is the formatted relative name (ex: CN=John Smith or CN=Smith, John)
* container is the formatted destination container (ex: OU=Sales,OU=East,DC=northamerica,DC=fabrikam,DC=com)
*
*/
private void ProvisionLDAPUser(MVEntry mventry, string MAName, string rdn, string container)
{
ConnectedMA ldapMA = mventry.ConnectedMAs[MAName];
if (ldapMA.Connectors.Count == 0)//make sure we don't have any pre-existing connectors
{
CSEntry cseLDAP = ldapMA.Connectors.StartNewConnector(
"user");//generically start a new user
cseLDAP.DN = ldapMA.EscapeDNComponent(rdn).Concat(container);//Concatenate the RDN and Container, ensuring proper formatting
cseLDAP.CommitNewConnector();//Commit the new connector
}
}
If you wanted to, you could bring the predetermination of the user object type out of the function, in case you wanted to bring the logic for the determination of object (ex: user vs. contact)
private void ProvisionLDAP(MVEntry mventry, string MAName, string rdn, string container, string objectType)
{
ConnectedMA ldapMA = mventry.ConnectedMAs[MAName];
if (ldapMA.Connectors.Count == 0)//make sure we don't have any pre-existing connectors
{
CSEntry cseLDAP = ldapMA.Connectors.StartNewConnector(objectType);//generically start a new object
cseLDAP.DN = ldapMA.EscapeDNComponent(rdn).Concat(container);//Concatenate the RDN and Container, ensuring proper formatting
cseLDAP.CommitNewConnector();//Commit the new connector
}
}
There isn't any error handling on CommitNewConnector, for handling duplicates or incorrect/missing container (OU). I like to handle outside of this function as I predetermine the rdn variable and container and if there is a caught error, I can handle it accordingly
try
{
ProvisionLDAPUser(mventry,
"Test Active Directory", String.Concat("CN=", mventry["displayName"].Value), "OU=Exchange Users,DC=test,DC=fabrikam,DC=com" );
}
catch (ObjectAlreadyExistsException)
...
}
This is helpful if there is a conflict on naming. Notice in my case, the RDN is the string literal "CN=" and the displayName attribute. I can ensure some uniqueness in the creation of that displayName attribute and not have to worry about ObjectAlreadyExistsException. If I don't, I can append an integer value or maybe use another attribute to append to the constructed RDN to ensure uniqueness.
More to come on this concept.
