Hi,

according to apache documentation in https://httpd.apache.org/docs/2.4/mod/mod_authnz_ldap.html#reqgroup, the full group DN must be specified:

----- 8< -----
Require ldap-group
This directive specifies an LDAP group whose members are allowed access. It takes the distinguished name of the LDAP group. Note: Do not surround the group name with quotes. For example, assume that the following entry existed in the LDAP directory:

dn: cn=Administrators, o=Example
objectClass: groupOfUniqueNames
uniqueMember: cn=Barbara Jenson, o=Example
uniqueMember: cn=Fred User, o=Example

The following directive would grant access to both Fred and Barbara:

Require ldap-group cn=Administrators, o=Example

---- >8 -----

HTH,
flo

I have got authentication working on my Apache 2.4 webserver, if I require a specific user. However, I would like to require one or more specific groups. I have tried the example given in the documentation:
      Require ldap-group
with no group name specified.

I get this result in my log files:

I have tried the following in the configuration:
        Require ldap-group cn=accounts
        Require ldap-group accounts
with  AuthLDAPGroupAttributeIsDN  set to both "on" and "off". Neither work:
