Powerbuilder 9 and LDAP Authentification

[Courtigu]

I work on Client Application developed with Powerbuilder 9?

Before entering in the application, a login and a password
is asked. I would like to authenticate with LDAP annuary
(Active Directory).

I've tried to put library furnitured by Sybase (see link,
http://www.sybase.com/detail?id=1058501#789) in my project
but I fail.

With this link you get a zip file called "pb2ldap.zip" which
contains Powerbuilder Libraries and dll files.

When I launch LDAP authentification : my program fails, it
cannot launch Java virtual machine.

I don't know why, has someone already tested these libraries
?

Thanks for all information you can put in this subject.

I have an example using the Win API function LogonUser which is a much
easier way of doing it.

Here is the documentation for LogonUser:

Thanks for your answer.

But I have 2 more questions :
1) If I attempt to log with a user and password which is not
a local account of the PC but which is an active directory
account known in the local network, can I use this function?
2) The function LogonUser doesn't require the IP address of
the named server on which Active Directory is running. How
does it find this server ?

Thanks for all information that could help me.

If you pass a value in the domain name argument, it will validate the user
against Active Directory on the Domain Controller. If you leave it blank as
in my example, it will validate it against local accounts.

My example Netquery has the function NetWkstaGetInfo which will return the
domain that the computer is a member of.

Excellent code, thanks a lot!!! Believe it or not I am still using PB
7 and this code was not working there. It does work on PB 11.5. Do you
now why ??

Update to above issue - I used following declerations and it worked on
PB 7 also. The change was to use logonuserA instead on LogonuserW as
the alias. all other declerations were kept as in your (Roland Smith)
post.

Function ulong WNetGetUser( &
string lpname, &
ref string lpusername, &
ref ulong buflen &
) Library "mpr.dll" Alias For "WNetGetUserW"

Function boolean LogonUser ( &
string lpszUsername, &
string lpszDomain, &
string lpszPassword, &
ulong dwLogonType, &
ulong dwLogonProvider, &
ref ulong phToken &
) Library "advapi32.dll" Alias For "LogonUserA"

Function boolean CloseHandle ( &
ulong hObject &
) Library "kernel32.dll"

Thanks Robert. Your code helps me a lot and it works with my
application in the local network of the customer.
