Password Generation in QIM

Hello,

I have below questions on password generation process in QIM;

a) Can someone provide details on the process of generation of password on QIM when a new user is created through a DataImporter Feed.

b) Do we have the concept of password policies to define the rules based on which passwords are generated/expire etc?

c) Also how can we attach password policies to different users so that passwords that are generated comply to specific password policy (can we do multiple password policies based on user type?).

Please point to relevant documentation that can be helpful.

Regards,

Amit
