Please help.

do you mean "attribute" instead of "attribuild"?

If you want to know, whether the attribute is supported you your LDAP Server you have to look in the Servers Shema.

Hi,

Oops....wrong spelling.
back to the topic. i am sure that the attribute is exist seeing that i can use others query method to get it. just happen that when i use the directory service, it is not there. so i really don't understand. please help

Where do you bind as an user with administration rights? I can't see the connection line. If you bind a anonymous, you probabaly don't have the rights for searching the wanted attribute.

ps: are you german?

Hi,

i am not german.
nop. this server do not require admin login. i use others connection also did not authenticate but it can work. thanks for your advice in advance.
