A partial list of LDAP clients is available on the WWW here:
http://www.umich.edu/~rsug/ldap/ldclients.html
please send additions and corrections to ldap-support@umich.edu
We have had some conversation with people at Qualcomm r.e. adding LDAP
support to Eudora. The outcome was much like with the Pine
developers: client developers in general are waiting for a "winner"
before committing to adding support for any of LDAP, Whois++, etc. I
encourage all LDAP devotees to ask your e-mail client vendor to support
LDAP now.
