I had wondered about the specification of the password hash type.

I chose SHA-512 as it seemed to be suggested in the 
passwordStorageScheme attribute described in Table 14.1 of the Redhat 
Directory Server Admin Guide, 
https://access.redhat.com/documentation/en-US/Red_Hat_Directory_Server/9.0/html-single/Administration_Guide/index.html. 
But now I come to re-read that doc it suggests perhaps that SHA covers 
all the SHA- variants, so I'll give it another go using {SHA}xxxxxxx as 
the userpassword specification.

I have also seen the userpassword attribute referred to in other places 
as userPassword and wondered whether the attribute name is case 
sensitive. Do you know?

Thanks for your input.
