Have you tried using ADSIEdit or ADSIView yet? (Does it work?)
---Yes i tried connecting using ldp.exe and it does work. Since it does not
require a username and password to connect it allows me to connect and shows
me search values if i do a search.
Does this work in a console app?
---I tried doing a desktop application using Vb.net. Gives me the same error
that i get through a web application. It bombs out at the line
osearcher.FindOne with the same stupid error "Unknown Error(0x80005000)"
> Is your LDAP string is correct?
---My LDAP String is correct i believe because i used the same string in the
windows support tool application ldp.exe as mentioned above and it works.
Probably i am not using it in the right format in my asp.net application and
you could guide me there. I have mentioned what i use in my first question to
which you replied
> Is " LDAP://directory.x.y/ou=People,dc=x,dc=y"; the actual LDAP string?
--- No this is just an example string. I have some values for x and y that
correspond to my ldap server. I can tell u these if you want.
> Is the IIS server trusted at the respective domain you're trying to
> search?
---I dont know because the LDAP server is on the college campus servers and
i have no access to that server. Also, as per your suggestion it should not
matter because if a desktop application should work then i dont need a web
application and we can leave IIS out of this.
> Have you tried filtering using another property (like SAMAccountName)?
--- I thought this property could only be used for windows 95,98,NT4
machines. If i am wrong please post an example with the use of this property.
I will appreciate that.
> You can also try using DirectoryEntry("LDAP...", null, null,
> AutheticationTypes.Secure);
---I tried using that. Still the same problem. Also as i mentioned i dont
need to use authenticationtypes.secure because i can bind anonymously to this
ldap server thats what the campus people who have this server tell me.
Please help me!! Thanks for all your help till now. I really appreciate your
looking into this problem. Looking forward to your reply.
