Most applications I know of that do "bind as user" to authenticate also 
permit you to specify a format string into which the user name is 
inserted (i.e. the format string is the dn, e.g. 
"uid=%u,cn=users,cn=accounts,dc=example,dc=com") -or- they do a search 
to discover the dn. If you application does not support either approach 
it's broken IMHO.

Reading passwords and/or password hashes is not supported for security 
reasons.
