APAR status

  • Closed as program error.

Error description

  • Its seen that the authorization may fail while using the LDAP
    authorization attribute, ie the attr_name of ldapAuthorizeUrl,
    as 'CN' or 'samAccountName' connecting to Active Directory LDAP
    server. In the failure cases, its seen that ACE is unable to do
    a valid mapping defined LdapAuthorizeAttributeToRoleMap even
    though the configurations are right.
    

Local fix

  • One can use 'DN' of group or memberOf attribute of user as LDAP
    authorization attribute.
    .
    eg :
    ldap://localhost:363/<user
    baseDN>?memberOf?sub?(samAccountName={{username}}) => using
    memberOf attribute of user
    ldap://localhost:363/<group
    baseDN>?dn?sub?(member={{dn}}) => using dn of group
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of IBM App Connect Enterprise V11 using administration
    security with LDAP authorization.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    Administration security authorization may fail when connecting
    to an Active Directory LDAP server and using the LDAP
    authorization attribute, ldapAuthorizeUrl, as 'CN' or
    'samAccountName'.  In the failure cases, it is seen that IBM App
    Connect Enterprise is unable to do a valid mapping defined in
    LdapAuthorizeAttributeToRoleMap even though the configuration is
    correct.
    
    An example of a valid <span style="background-color:rgb(255,
    255, 255)">ldapAuthorizeUrl configuration that may fail is:
    </span>
    
    ldap://server:port/<basedn_of_group>?CN?sub?(member={{dn}})
    
    A work-around in such a case is to use memberOf attribute of
    user object as below:
    
    <a
    href="ldap://coaldap.coacd.org:389/DC=coacd,DC=org?memberOf?sub?
    (samAccountName={{username}})">ldap://server:port/<basedn_of_use
    r>?memberOf?sub?(samAccountName={{username}})</a><span
    style="background-color:rgb(255, 255, 255)"> </span>
    

Problem conclusion

  • The product no longer fails to do the LDAP authorization role
    mapping when the group attribute name is 'CN' or '<span
    style="background-color:rgb(255, 255,
    255)">samAccountName'.</span>
