Hello, I am trying to set the ldap-auth plugin to be on all apis.
My configuration for this plugin is:
```
curl -X POST http://localhost:8001/plugins/
--data "name=ldap-auth"
--data "config.hide_credentials=false"
--data "config.ldap_host=10.180.20.1"
--data "config.ldap_port=389"
--data "config.base_dn=OU=Employees,OU=COMPANY-USERS,DC=test,DC=com"
--data "config.attribute=cn"
--data "config.cache_ttl=60"
```
I consume the api using
```
curl -H "Authorization: LDAP " http://localhost:8000/details/
```
Everything from here is working fine, But when i set the **config.attribute=samaccountName**
The kong logs gives me
> Error: The supplied credential is invalid.
> Details: 80090308: LdapErr: DSID-0C0903D0, comment: AcceptSecurityContext error, data 52e, v2580
Attribute that works are cn and name but anything else do not like samaccountName or email.

Hello,
What you are describing should in fact work.
Just to clarify: can you confirm after changing the attribute to `samaccountName`, you also changed the base64 calculation used in curl so that it used `samaccountName` instead of `cn`?

Thanks for responding,
I did change it so be the base64(samaccountname:password) and it is still giving me the same error.
I am not sure if there is other place i should be looking at. I have tested the samaccountname with the a python code to authenticate and it was working fine.

Anyone can help?

Hello,
I have the same issue.
I think the kong ldap plugin is considering only CN attributes. I
I’ve opened an issue on github:
