Known Limitations and Issues

 

The list below outlines known issues, but feedback is still welcomed on any items that are important to you.

 

Windows 95/98/Me

 

Hyena will not run under Windows 95, Windows 98, or Windows Me; it must be executed from a workstation or server running either Windows NT, Windows 2000/2003, or Windows XP.

 

Share Permissions

 

Hyena’s share permission management functions are nearly identical to the native Windows share functions, with a few exceptions as noted below:

 

Write Access Type – Hyena allows an access type called "Write" for share access permissions. Write access permits both read and write, but not delete access. Microsoft's utilities often do not recognize this attribute and will display any Write access types as "Special Access" or "Full Control" instead.

 

Unavailable User/Group – When Hyena accesses the properties for a share's security attributes, it must retrieve the text representation of each user/group that has been granted or denied access. If the user/group belongs to a remote computer (such as a domain controller or trusted domain), and if the remote computer is down or unresponsive, an error message will be displayed, and the remote user/group will NOT be displayed in the access list. If the permission list is modified, the inaccessible remote user/group will be removed from the permission list.

 

This situation is relatively rare, and will only occur in cases where security permissions are spread across multiple servers and domains and one of the security providers is down.

 

Local Groups – Hyena allows inclusion of local groups from both the current domain and all trusted domains into any share permission list. Windows utilities also support this operation, but the supporting documentation is sparse and difficult to interpret.  This feature of NT only works with user-defined local groups, NOT the built-in local groups, such as Backup Operators, Print Operators, etc. Unfortunately, NT does not allow an easy determination if a local group is built-in or user-defined, so the local group permission list does include all of the local groups. If a built-in local group is added from a remote domain, an error will occur when an attempt is made to save the new permission list.

 

Trusted Domains – Hyena does not try to determine if a given domain has an established trust with another domain. This makes it appear possible to include user/group permissions from non-trusted domains, when this is not really possible. Windows NT does not report an error when an attempt is made to include user/group permissions from non-trusted domains.

 

Use of the "*" key in the Tree View Window

 

The standard Windows tree window, which is used in the left view window in Hyena, has several standard keystrokes that are built-into the behavior of this control. One of them involves the use of the "*" key, that when pressed, will automatically expand all of the items and sub-items under an object. This can be useful in some cases, but for some objects, this feature can cause near lockups of the client workstation running Hyena, due to the number of potential sub-items affected. Once this feature is invoked, the process must be terminated (End Tasked) in order to stop it.

 

Last Known User Log on and Log off

 

Windows NT : When viewing the information for a group of Windows NT users (User Details function), Hyena displays the last known log on and log off information that is returned from the primary domain controller (PDC). However, Windows NT and Windows 2000 do not centrally store the log on information for users, and therefore this information can be scattered across all of the domain controllers on your network. Hyena does not support polling all of the domain controllers to get this information for multiple users due to the performance limitations of doing this.  Since the information may still be somewhat useful, it will continue to be displayed on some views. However, this information is not displayed by default. Displaying the last log on/log off information can be enabled/disabled in the Tools->Settings->User dialog.

 

Windows 2000/2003 : Windows 2000/2003 Active Directory also does not centrally store the log on information for users, and the logon-related attributes such as lastlogon will only reflect the data retrieve from a single domain controller.  

 

Note that you CAN display the last log on/log off information for individual users in Hyena, by using the View Logon Information function.  This option supports retrieval of the log on information from all of the domain controllers for the given user.

 

To view the last logon information for multiple users, use Exporter Pro, which has options to report the last logon information for both Windows NT and Windows 2000/2003 domains.  See the Exporting topic for more information on Exporter Pro.

 

User Primary Group

 

Modification of the primary user group for multiple users is not supported.

 

Exchange 5.5 Limitations

 

Hyena’s custom integrated Exchange support has the following limitations. Note that Hyena will by default use the installed User Manager Extensions interface into Exchange, which does not have these limitations. To enable / disable the type of Exchange integration, change the value of the “Enable Hyena’s Custom Exchange Integrations Options” setting under the Tools->Settings->Exchange 5.5 dialog. See the Exchange Options and Setup section for more information on Exchange options.

 

“Hide from Address Book” feature not supported – Hyena is not able to find mailboxes that are setup with the “Hide from Address Book Feature”. We do not see a workaround for this problem, as Exchange “hides” the directory entry from the global address list that is used to perform the lookup.

 

Possible problem with finding your own Exchange mailbox – There may be a limitation in the mechanism used to lookup the mailbox for the currently logged in user. One possible workaround for this problem is to setup a separate Exchange profile that uses a different user account.

 

Default Email Addresses are not shown in Email Address dialog – When adding new users, Hyena will not display the default email address that will be created by Exchange when new users are added. However, they will be created automatically when the mailbox is added.
