I never used MantisBT with LDAP, so I can't really help.

Where do you want to store the key to decrypt the password?

Maybe better quality because Linux/Apache/MySQL/MantisBT is a combination which is used by more users than Windows/Apache(or IIS)/MySQL(or SQL-Server)

Yes
For future usage of the forum: Please don't mix different questions in one post. It's hard to follow up and reading "LDAP" in the title does not match the whole topic.
