Problem
At creation time, you want to assign the issue first to the manager of the current user, to decide and categorize the issue. The problem is that the relationship between the current user and the manager is not declared in JIRA (as a project admin, for instance), but in the LDAP.
Solution
create_postfunction.sil
string mgr = ldapUserRecord("manager", "(sAMAccountName=" + currentUser() + ")"); //get the current user's manager DN
string cnUser = substring(mgr, 0, indexOf(mgr,",")); //establish the cn, this is the manager user (that may depend on your setup)
string mgrUserName = ldapUserRecord("sAMAccountName", cnUser); //again, a lookup in the Active Directory to get the manager
//Note: these LDAP calls are automatically cached, so performance gets better if it is found in cache
if(userExists(mgrUserName)) { //make sure this is defined in JIRA
assignee = mgrUserName;
} else {
//fallback to project admin
assignee = projectPM(project);
}
This postfunction should be the last in the call chain at create.
All you have to do now is to configure your LDAP and there you go !
The above assumes that the windows account name is the same the user is using to access JIRA. This is really dependent on the AD setup.
