Understanding the User. Account. Control Attribute in Active Directory. Dougga here. Not a password policy blog post, I am finally off of that issue. But I couldnt help myself and included something about passwords in this post lt grin. Users and Computers have and attribute called User. Account. Control that dictates some behaviors and characteristics of these accounts. Active Directory administrators should be aware this attribute and how to interpret it. The value is a bitmask and features are enabled by turning on or off various bits along the mask. There are many articles on this topic here is one, so I am simply giving you some examples to work through and a homework assignment at the end. Active Directory User Attribute Disabled Children' title='Active Directory User Attribute Disabled Children' />When viewing the User. Account. Control attribute in ADSI edit or LDP, the value is represented in Decimal or Hexidecimal. So, it is important to know how to convert the values. And since it is a bitmask, binary is needed as well. I am going to walk you through two short examples and give you a few to do on your own. Active Directory User Attribute Disabled' title='Active Directory User Attribute Disabled' />I am not going to teach you how to convert the values, so use a calculator as needed. Further down in this blog is a bitmask table with explanation of the values. I copied the table from protocol specification MS ADTS. Review the table and you may find some familiar settings that you may have encountered. The table is needed for working the examples and homework to map the one or two letter values. On with the examples and homework. Example 1 The default value for domain controllers 5. Convert 5. 32. 48. Bin 1. 00. 0 0. 01. Hex 0x. 82. 00. 0Place the binary value on the top row to interpret the bit using the table below. For domain controllers the default value for domain controllers lines up TD and ST. Note The second row is a counter for the bit 0 3.

This can be reproduced by creating a computer account before joining the computer to the domain and promoting the machine to become a domain controller. In addition to the Active Directory Rap as a Service, DCdiag will discover the issue with the following output lt SNIP FROM DCDIAG Starting test Machine. Account. Checking machine account for DC DC1.

Importing users into Active Directory CSV, ExcelThe import file can be formatted using the CSV comma separated value format or Excel XLS 2. XLSX Excel 2. 00. The column headers in your file CSVXLS,XLSX should contain the name of the Active Directory Attribute you want to add the data to. A list of column headersattributes can be found below. The columns can be in any order and the column headers are not case sensitive but obviously must be spelt correctly for the program to recognize them, if it comes across a column it doesnt recognize it will ignore that column. In the example shown below Im using Excel to construct the file and using wildcards to speed up the creation of the file. The first row 1 contains the column headers, these are the attribute names such as given. Name first name. You dont need to use all the attributes names just those you need, the minimum required to create a new users are shown below. This example file would create 5 new users. Import users from SQL Server and ODBC sources. You can use SQL Server or Oracle data source to store the users to be imported or updated. Example connection strings to use within AD Bulk Users are below. Microsoft SQL Server. Servermydbsrvmy. Instance. Name Databasemy. Data. Base User Id Password Oracle Database. Data SourceDESCRIPTIONADDRESSLISTADDRESSPROTOCOLTCPHOSTdbsrv. PORT1. 52. 1CONNECTDATASERVERDEDICATEDSIDPROD User Id Password Updating Existing Active Directory User Accounts. AD Bulk Users can be used to updatemodify existing Active Directory Users. This is done by adding the column header Modify to the import file and setting the value to TRUE. Wpa Psk Cracking Software Download more. To update the description and telephone. Number attributes for 5 users you would use a file saved as CSV or Excel similar to the example below. The s. AMAccount. Name username is used to locate the user in Active Directory, the Modify column with a value of TRUE tells the program to update an existing user. The other columnsattributes are those to be updated, in this case description and telephone. Number. If you want to update many attributes at once you can, simply add the additional column headers to your import file. For example s. AMAccount. Name,Modify,description,telephone. Number,initials,employee. ID,password. Command Line Arguments. AD Bulk Users 4 contains a built in scheduler so you dont need to use the command line to automate imports but if you prefer to use the Windows Task Scheduler or have another reason to use the command line you can. Use ADBulk. Users. CLI. exe from the command line. You can find the syntax and command line examples for ADBulk. Users. CLI. exe below. ADBulk. Users. CLI. Microsoft Terminal Services Support. Import and Modify Terminal Services Home Folder and Profile Path for users. See Screenshot. Microsoft Exchange Support. Create Exchange Server Mailbox for users. See Screenshot. Wildcards. To speed up the creation of your import filetable you can use wildcards throughout your CSV file or table. You can create your own wildcards by clicking Wildcards in the ribbon. AMAccount. Name columnfirstname reads the value found in the given. Name columnlastname reads the value found in the sn columngiven. Name reads the value found in the given. Name columnsn reads the value found in the sn columns. AMAccount. Name reads the value found in the s. AMAccount. Name columnuser. Principal. Name reads the value found in the user. Principal. Name columninitials reads the value found in the initials columnemail reads the value found in the mail columnfirst. Namefirst reads the first letter of the value found in the given. Name columnfirst. Namelast reads the last letter of the value found in the given. Name columnlast. Namefirst reads the first letter of the value found in the sn columnlast. Namelast reads the last letter of the value found in the sn columnTo create a new wildcard click the Add button then enter a wildcard name such as employee. ID and then select a column that the wildcard will read. You can use a Regular Expression if you want to manipulate the value such as reading the first or last character. Home Folders. To set the users Home Folder add the column header home. Directory to your import file, the value would be a UNC path e. AMAccount. Name value, to set the drive letter to be mapped on logon use home. Drive with a value like H or P. You can use a local folder such as e User. Folder column with the local path followed by a semicolon and the drive letter, e. E homedrives z. Creating the home folder. The program can create the home folder whilst creating the user, use the column create. Home. Directory with the value set to True, this requires the home. Directory column. The program will create the home folder within the share specified in the home. Directory value, for example if the value is servernameUsersusername then the program will create the a folder named jsmith username is jsmith with the share Users. By default the user will have Modify permission to their home folder, you can change this to Full Control under OptionsHome Folder. Alternative method of creating the users home folder. An alternative method of creating home folders is to specify the path and drive letter under OptionsHome Folder, this give you some additional options. Under OptionsHome Folder you can specify the permissions used and the option to create the home folder as a share, if the folder already exists then the program can re apply permissions if necessary. To create the users home folder add the column create. Home. Folder to your import file and set the value to TRUE for each user. Importing into multiple OUs. To import users into multiple OUs from the same import file add the property destination. OU to your import file. An LDAP path placed in this field results in the user being imported into that OU. This overrides the Active Directory Container OU found on the settings tab. If the user has a destination. OU value present in the import file then the user is imported into that OU otherwise the user is imported into the OU found on the settings tab. Manager Property. Within Active Directory a users Manager Organization tab is stored using the distinguished. Name of the manager for example CNJohn Smith,OUManagers,DCDomain,DCCom. To set a users manager using AD Bulk Users you can use the distinguished. Name, s. AMAccount. Name username of the manger or the employee. ID of the manager version 5. Below are three examples s. AMAccount. Name,Modify,managerpjones,True,jsmith using managers s. AMAccount. Names. AMAccount. Name,Modify,managerpjones,True,1. IDs. AMAccount. Name,Modify,managerpjones,True,CNJohn Smith,OUManagers,DCDomain,DCComWhen using the managers s. AMAccount. Name or employee. ID the program will need to search AD for the managers distinguished. Name so these lookups will be slower than using the distinguished. Name. Custom or unlisted attributes. It is possible to add additional and custom attributes to the program. Click Attributes in the ribbon to add a unlisted or custom attribute. Supported Attributes ListColumns in your file can be in any order and the column headers are not case sensitive.
