connect through Oracle feature

[mubashir]

Oracle has a feature whereby one can connect as another user as long as he has the connect through privilege granted to him by the sys dba to connect as another user
Using sqlplus or TOAD we can connect as follows
username: userA[userB]
password :userA password

we then connect as userB. However i tried this with plsql developer and it gives invalid username password. Any advise how i can use this in PL/SQL developer

This can be an Oracle Client version issue. Go to Tools > Preferences > Oracle / Connection to select the Oracle Home with the newest version.
