Add Security Group Members Error RRS feed

  • Question

  • Hi,

    I'm trying to add resources to security groups using PSI but I'm getting the following error when saving the security groups dataset:


    Message: ProjectServerError(s) LastError=GeneralUnhandledException Instructions: Pass this into PSClientError constructor to access all error information

    Here is the code I'm using to add security group members:

    foreach (SearchResult sr in selectedResources)
                        if (!string.IsNullOrEmpty(sr.SecurityGroups))
                            string[] resourceSecurityGroups = sr.SecurityGroups.Split(new char[] { Convert.ToChar(",") });
                            for (int index = 0; index < resourceSecurityGroups.Length; index++)
                                Guid WSEC_GRP_UID = new Guid(securityGroupsDataSet.SecurityGroups.Select(securityGroupsDataSet.SecurityGroups.WSEC_GRP_NAMEColumn.ColumnName + " = '" + resourceSecurityGroups[index].Trim() + "'")
                                SvcSecurity.SecurityGroupsDataSet.GroupMembersRow member = securityGroupsDataSet.GroupMembers.NewGroupMembersRow();
                                member.RES_UID = sr.RES_UID;
                                member.WSEC_GRP_UID = WSEC_GRP_UID;

All replies

  • the error above is to general

    as requested above, you should us PSClientError object to get more details on this error


    see code sample here:

  • Thanks for your reply.

    I already used that code but the exception is not even catch as SoapException.

  • More details....

    I'm using Visual Web Part to add the security group members. Also, I tried the same code from Windows Application and it worked just fine!

  • What type of exception is actually thrown?


    There should be a full message looking like this: "System.Web.Services.Protocols.SoapException: ProjectServerError(s) LastError=GeneralUnhandledException Instructions: Pass this into PSClientError constructor to access all error information"


    Anyways it looks like a possible credentials issue, which is a common difference between windows apps and web apps.

    See if using a hard coded network credentials of a domain user will work (instead of using default credentials) on the securityClient object
