How to send gpg key to LDAP server with authorization?

Question

linux

SUBJECT.
I try this way:

gpg --keyserver ldap://192.168.1.1:389 --keyserver-options 'binddn="uid=admin,ou=PGP Users,dc=example,dc=com"' --keyserver-options passwd=passwd -- send-keys XXXXXXXXXXXXXXXX

But I get a message:

gpg: keyserver option 'binddn' is unknown
gpg: keyserver option 'passwd' is unknown
gpg: Sending key XXXXXXXXXXXXXXXX to ldap://192.168.1.1:389 gpg: Failed to send to keyserver: Requires (more) strong gpg
LDAP authentication
: Failed to send to keyserver: Requires (stronger) LDAP authentication

Can you please tell me how to send using the command line.
