In SDL Tridion 2011 the mapping of a user with a group (or vice versa) in CME can be done in two ways - Either you can select open a User and add it to a group from the Members tab or alternatively you can select open a Group and add the user to it from the Members tab.
However, SDL Tridion 2013, I observed that you can add a User to the Group but you can not Open a group and add user to it.
Just want to know if this is desired behaviour in 2013 version or I am missing something.
Also, if this is desired behaviour, is there some rationale behind it that I am not able visualize (except the load time may be too high in case AD (or LDAP) contains huge number of Users)
Can someone share their experience?
