Hi,

In a recent project we have decided to use umbraco for a intranet solution. There is a number of posts describing the problem with umbraco as a intrenet and AD autentication. But we decided to give it a try anyway. Our goal was to create a multiprovider that lets us use the umbraco backend as usual and also use the umbraco methods for useraccess on the site.

Both of these scenarios work and all the AD groups load perfectly into the umbraco backend and so on, but there is a couple of problems that i can't wrap my head around. When recycling the applicationpool or doing something that makes the site recycle i am always presented with the same exception. Also if i am to quick on refreshing i am presented with "unable to load appdomain", but this does not happen everytime.

Could not load file or assembly 'Examine.XmlSerializers' or one of its dependencies. The system cannot find the file specified.

I can't get my head around why it is trying to load examine. For a test i included all the dll files in the solution for my provider but that did not help. I will provide the GetRolesForUser code below. If any more code is neede i just say so and i will post that also.

public override String[] GetRolesForUser(String username)
        {
            // If SQL Caching is enabled, try to pull a cached value.
            if (_EnableSqlCache)
            {
                String CachedValue;
                CachedValue = GetCacheItem('U', username);
                if (CachedValue != "*NotCached")
                {
                    return CachedValue.Split(',');
                }
            }
            ArrayList results = new ArrayList();
            using (PrincipalContext context = new PrincipalContext(ContextType.Domain, null, _DomainDN))
            {
                try
                {
                    UserPrincipal p = UserPrincipal.FindByIdentity(context, IdentityType.SamAccountName, username);
                    var groups = p.GetAuthorizationGroups();
                    foreach (GroupPrincipal group in groups)
                    {
                        if (!_GroupsToIgnore.Contains(group.SamAccountName))
                        {
                            if (_IsAdditiveGroupMode)
                            {
                                if (_GroupsToUse.Contains(group.SamAccountName))
                                {
                                    results.Add(group.SamAccountName);
                                }
                            }
                            else
                            {
                                results.Add(group.SamAccountName);
                            }
                        }
                    }
                }
                catch (Exception ex)
                {
                    throw new ProviderException("Unable to query Active Directory.", ex);
                }
            }
            // If SQL Caching is enabled, send value to cache
            if (_EnableSqlCache)
            {
                SetCacheItem('U', username, ArrayListToCSString(results));
            }

            return results.ToArray(typeof(String)) as String[];
        }

Thankful for any help at all. Cheers.
