create 200 users and assign Hybrid app in SCC

Dear All.

            In our organization around 200 employees are there, Is it required to create all users in SCC and assign Hybrid Application?

We tried by creating one user in SCC and try to register in two mobiles with same user name and activation code.

In one mobile it got registered but in another mobile it gave “Wrong Device For Code” error in the log.

WE can't user LDAP connection because,

In case of LDAP user name we can see in SCC after his registration. We have to wait for the user to register and then assign the app.

How to solve this issue?

Thanks in advance
