Require ldap-group fails with Kerberos authentication and AuthLDAPSearchAsUser

Solution Verified - Updated -


  • We are trying to configure a private zone with apache modules auth_gssapi to SSO and authnz_ldap to restrict access by LDAP group, but it doesn't work. Our configuration is:

    <Location "/mypath">
        AuthType GSSAPI
        AuthName "Kerberos Login"
        GssapiAllowedMech krb5
        GssapiCredStore keytab:/etc/httpd/conf/httpd.keytab
        AuthLDAPSearchAsUser on
        AuthLDAPGroupAttribute member
        AuthLDAPUrl ldap://,cg=org?userPrincipalName?sub
        Require ldap-group cn=mygroup,ou=groups,dc=myorg

    However, even though the user authenticates correctly and is correctly assigned to the group, the authorization fails.
