FWIW, LDAPv3 and related protocols and/or code expecting to obtain
authentication data from an LDAP database uses:

	{crypt}SDFGgskh351!@
	{md5}XXXXXXYYYYYZZZZ

(The passwords here are sames that aren't correct).

The point is that the algorithm is identified by a leading encoding
tag using the SASL ID for the thing.
