When "Add managed System" template is executed on a double stack sytem adding one of the clients of the central ABAP systems as managed systems then the webservice destination created will have username as "init" and password as "init" set.
This problem occurs only when one of the clients of ABAP central system is added to the landscape.
This bug is a side effect of another fix that was done before which required that CCMS setup page is blocked for central ABAP systems other than the default client.
CCMS setup for the default client of the central ABAP system is anyways done when "Configure NWA for Double stack" template is executed.
In order to add any client of the central ABAP system to the landscape without any of the above mentioned problems then please upgrade the SCA LMCFG to this patched version.
