What you mean by not synced with the AD, do you expect local user created on the CUCM get updated on the AD. if true this is not possible.
When preforming a full syn CUCM will pull the users on AD OU mentioned on the CUCM LDAP directory page and based on if any LDAP filter applied.
If the scheduled synchronisation does not bring the user in, a manual sync would not do any difference. Do you have all the required information set on the user in AD for it to be brought over by the synchronisation and is the user placed in an OU that is visible to the search path set on the LDAP directory?
In general it would not be a good idea to run a synchronisation during production hours. It is best done during off hours. If you want to do a manual sync you’ll do that on the LDAP directory configuration element in CM by selecting Perform Full Sync Now.
Yes i becomes the LDAP synced user.
To do a manual sync, you must do a "perform full sync" for LDAP directory page. When you do a Sync, if there exist a user in AD which is not with CUCM will be imported.
If the user id is exactly the same on the local end user account as for the account in the LDAP server it should be overwritten, aka converted into a LDAP synced user.
