[sork] ldap problem

[David Chang]

Hi all:
I saved ldif file as UTF-8 format which convert from BIG-5,and then use ldapadd
shell command to add these user account into openldap server (2.0.25) for our
organization.

After this,in turba i also have a address book called "local_ldap" which include
all user account for our organization .All of the user accounts look right in
Chinese format in Turba's Browse (see
http://210.241.49.67/~txg16/tmp/920417_1.jpg ) ,But in Account project i got
these error messages (also see http://210.241.49.67/~txg16/tmp/920417_2.jpg ):

Question:
Does /account/conf/config.php need options such as charset,ldap-vesion specified
in it(like /turba/conf/source.php) ,if ldap driver selected ?
