I have the following Distinguished Name to find a user in my Active Directory: CN=ronaldo.lanhellas,OU=SERVICOS_EXTERNOS,OU=Departamento de TI,OU=Record Belem,DC=recordbelem,DC=com,DC=br
This works fine, but I created a GROUP called CEDOC2 and I put the user "ronaldo.lanhellas" inside this group, see:
Now I'm trying to access the user ronaldo.lanhellas inside this group, with this DN:
CN=ronaldo.lanhellas,CN=CEDOC2,OU=_Sistemas,DC=recordbelem,DC=com,DC=br but i got "Invalid Credentials"

When I use graph API withinh POSTMAN in order to add a guest user to a group I process as follow :
Add the /invitations endpoint to add my user ( I do not use email invitation)
Then I can see from my AD users that it has been added properly
Next I user the /groups/{Group ID}/members/$ref to add the created users in step 1
Then I can see from my AD that users has been added to group right a way
Then this exact steps, I add it in a script that is executed at a dedicated time as follow: 1. use the /invitations endpoint to add my user and Send an invitation by email 2. The return userID by first call is then used to add right away the user to the group by using the /groups/{Group ID}/members/$ref endpoint with body set as
{ "#odata.id": "https://graph.microsoft.com/v1.0/directoryObjects/{userID}" }
Then response to add user to group is successfull
Then what is strange is that when I check in my AD , I can see the user which has been created BUT I do not see that user as a member of the group it has been added. It is not displayed while no error was return during the API call
Does it means it takes some time to get it visible ? Does it means that user need to validate the invitation before it is added to the group ?
Thanks for your help
regards
That was my mistake,
I get a scrip flag error which prevent the api to complete
I am using Delphi 10.3 and IPWorks LDAP component. I can modify most attributes without any issues, such as unicodePwd, givenName, and mail. However, for the userAccountControl attribute of a user, I am unable to set ADS_UF_PASSWD_CANT_CHANGE, of course after successfully binding as an administrator with secure connection and supplying correct DN, because if the connection is not secure, it is impossible to modify the password:
const
ADS_UF_NORMAL_ACCOUNT = 512;
ADS_UF_DONT_EXPIRE_PASSWD = 65536;
ADS_UF_PASSWD_CANT_CHANGE = 64;
ADS_UF_LOCKOUT = 16;
ipaLDAP1.DN := searchResultDN;
ipaLDAP1.AttrCount := 1;
ipaLDAP1.AttrType[0] := 'userAccountControl';
ipaLDAP1.AttrValue[0] := IntToStr(ADS_UF_NORMAL_ACCOUNT + ADS_UF_DONT_EXPIRE_PASSWD + ADS_UF_LOCKOUT + ADS_UF_PASSWD_CANT_CHANGE);
ipaLDAP1.AttrModOp[0] := amoReplace;
ipaLDAP1.Modify();
It is strange that I can not modify ADS_UF_PASSWD_CANT_CHANGE. It doesn't take effect on the user. When I check the user, this attribute is still unchecked. I don't understand why.
userAccountControl is a bitmask, so you should be using the or operator to combine flags, not the + operator.
But, more importantly, according to How to use the UserAccountControl flags to manipulate user account properties:
PASSWD_CANT_CHANGE
Note: You cannot assign this permission by directly modifying the UserAccountControl attribute. For information about how to set the permission programmatically, see the "Property flag descriptions" section.
Where the "Property flag descriptions" section says:
PASSWD_CANT_CHANGE - The user cannot change the password. This is a permission on the user's object. For information about how to programmatically set this permission, visit the following Web site:
Modifying User Cannot Change Password (LDAP Provider)
That page, in turn, says:
The ability of a user to change their own password is a permission that can be grant or denied. To deny this permission, set two ACEs in the security descriptor discretionary access control list (DACL) of the user object with the ADS_ACETYPE_ACCESS_DENIED_OBJECT ace type. One ACE denies the permission to the user and another ACE denies the permission to the Everyone group. Both ACEs are object-specific deny ACEs that specify the GUID of the extended permission for changing passwords. To grant this permission, set the same ACEs with the ADS_ACETYPE_ACCESS_ALLOWED_OBJECT ace type.
The following procedure describes how to modify or add ACEs for this permission.
To modify or add the ACEs for this permission
Bind to the user object.
Obtain the IADsSecurityDescriptor object from the ntSecurityDescriptor property of the user object.
Obtain an IADsAccessControlList interface for the security descriptor from the IADsSecurityDescriptor.DiscretionaryAcl property.
Enumerate the ACEs for the object and search for the ACEs that have the change password GUID ({AB721A53-1E2F-11D0-9819-00AA0040529B}) for the IADsAccessControlEntry.ObjectType property and "Everyone" or "NT AUTHORITY\SELF" for the IADsAccessControlEntry.Trustee property.
Note: The "Everyone" and "NT AUTHORITY\SELF" strings are localized based on the language of the first domain controller in the domain. Because of this, the strings should not be used directly. The account names should be obtained at run time by calling the LookupAccountSid function with the SID for "Everyone" ("S-1-1-0") and "NT AUTHORITY\SELF" ("S-1-5-10") well-known security principals. The GetSidAccountName, GetSidAccountName_Everyone, and GetSidAccountName_Self C++ example functions shown in Reading User Cannot Change Password (LDAP Provider) demonstrate how to do this.
Modify the IADsAccessControlEntry.AceType property of the ACEs that were found to ADS_ACETYPE_ACCESS_DENIED_OBJECT if the user cannot change their password or ADS_ACETYPE_ACCESS_ALLOWED_OBJECT if the user can change their password.
If the "Everyone" ACE is not found, create a new IADsAccessControlEntry object that contains the property values shown in the table below and add the new entry to the ACL with the IADsAccessControlList.AddAce method.
If the "NT AUTHORITY\SELF" ACE is not found, create a new IADsAccessControlEntry object with the same property values shown in the table below except the Trustee property contains the account name for SID "S-1-5-10" ("NT AUTHORITY\SELF"). Add the entry to the ACL with the IADsAccessControlList.AddAce method.
To update the ntSecurityDescriptor property of the object, call the IADs.Put method with the same IADsSecurityDescriptor obtained in Step 2.
Commit the local changes to the server with the IADs.SetInfo method.
If either of the ACEs were created, you must reorder the ACL so that the ACEs are in the correct order. To do this, call the GetNamedSecurityInfo function with the LDAP ADsPath of the object and then the SetNamedSecurityInfo function with the same DACL. This reordering will occur automatically when the ACEs are added.
The following table lists the IADsAccessControlEntry object property values.
AccessMask
ADS_RIGHT_DS_CONTROL_ACCESS
AceType
ADS_ACETYPE_ACCESS_DENIED_OBJECT if the user cannot change their password or ADS_ACETYPE_ACCESS_ALLOWED_OBJECT if the user can change their password.

There is a fairly lengthy code example provided on the same page.
I created a user in active directory 2003 , with the name mikedan as logon name later i went to the user properties and changed the logon name(for example to mikedannew) ,but when i go to the pc within the domain and try to access using the new login name (mikedannew) this is not working ! and when using the full upn name like mikedannew#domain.local this is working , also when using the sam name (domain\mikedan) which was not changed in my case , this is working too ,but typing the new logon name only not working ! .
So how can i change the user logon name only ?!
Just as Am_I_Helful said, you just changed the logon name, so you could use the new UPN(mikedannew#domain.local) to log in. And the User Logon Name(pre Windows 2000) is still the previous (domain\mikedan) not the new (domain\mikedannew). If you want to log in with the new name(user#domain.com or domain\user), you need to change both of them.
I’m trying to get Active Directory authentication working with Eucalyptus, but I’m not able to login to the console with the configured credentials. I’ve the following in my .lic file:

I’ve tried every combination of username, DOMAIN\username, username#domain that I can think of, but I still can’t login to the Eucalyptus console. Any suggestions?
Thanks,

Ok, so in answer to my own question, it appears as if it was working. After logging into the console using the admin login credentials created during the install/configure, I was able to see that the users were being created correctly. I made one small tweak to the .lic file, namely I set the id-attribute to use sAMAccountName rather than cn to meet user expectations for their login.
"users":{
"base-dn":"MY_BASE_DN”,
"id-attribute":"sAMAccountName",
"user-info-attributes":{
"displayname":"Full name"
},
"selection":{
"filter":"(&(objectClass=organizationalPerson)(objectClass=user))"
}
Also, I failed to pass in the the account name when running the euare-userlistbypath, namely:
euare-userlistbypath --as-account mygroup
Running with the account retrieves the user list as expected.
I am using this in ldif file to set the password.

replace:unicodePwd
unicodePwd:Krisv

I suggest using Apache Directory Studio to manage your LDAP directory. It should help avoiding that sort of problem.
In Apache Directory Studio, you can change a user password by double clicking the userPassword attribute description. This will open the Password Editor, where you can verify the current password or enter a new password.
Using Apache Directory Studio:
Open Directory Studio and connect to your repository.
Search/navigate to the user you want to modify.
To add a password, click the New Attribute button or menu LDAP > New Attribute (or SHIFT-CMD-+).
Enter Attribute type userPassword then click Next if you want to enter optional language tags, otherwise click Finish.
Password Editor opens. Enter and Confirm the new password, and select your hash method (don't leave it at the default plaintext!) then click OK.
You should now see a userPassword attribute in the list of user attributes.
If you want to change a password attached to an entity, locate the entity in Directory Studio, right-click and select Extended Operations > Password Modify. Or, locate the userPassword attribute for the entity and double-click it, or select and press F7. The Password Editor will be invoked and you can enter previous/new passwords. Note that modifying the password will require authentication using the bind DN.
