i have installed "OXtender for Business Mobility", and all work fine, i test and is ok.

When i active for context work fine:

/opt/open-xchange/sbin/changecontext -c 9 -A oxadminmaster -P password --access-usm on --access-active-sync on

but when i try to active per user, dont work.

/opt/open-xchange/sbin/changeuser -c 9 -A oxadminmaster -P password -u MYUSER --access-usm on --access-active-sync on

in option "-A" I try oxadminmaster, cpanelmaster1, oxadmin...

see error:

[root@ox ~]# /opt/open-xchange/sbin/changeuser -c 9 -A cpanelmaster1 -P PASS -u MYUSER --access-usm on --access-active-sync on

user MYUSER in context 9 could not be changed:

Server response:

No such user cpanelmaster1 in context 9

how i fix this ?
