    <p>I'm trying to programatically create a new Active Directory user setting the sAMAccountName attribute with a value larger than 20 chars.</p> <p>When I call the DirectoryEntry.CommitChanges(), I get the error:</p> <blockquote> <p>00000523: SysErr: DSID-031A0FB6, problem 22 (Invalid argument), data 0</p> </blockquote> <p>If I try to create a new user setting the sAMAccountName smaller than 20 chars everything work.</p> <p>Before someone says the the limit of the sAMAccountName is 20 chars, I want to point out that if I try to create the same user having the sAMAccountName more than 20 chars using the Windows tool "Active Directory Users and Computers" everything works. I can see the new entry in AD using the LDP tool and the entry has the sAMAccountName with more than 20 chars.</p> <p>Why can't I create the user programatically using .NET?</p> <p>Below is the code I'm using:</p> <pre><code>Using objDirEnt As DirectoryEntry = New DirectoryEntry("LDAP://my.domain.com/cn=Users,dc=my,dc=domain,dc=com", "username", "Password", AuthenticationTypes.Secure Or AuthenticationTypes.Sealing) Using usuario As DirectoryEntry = objDirEnt.Children.Add("CN=aaaaaa bbbbbbbbbb ccccccccc (aaaaaa.bbbbbb.ccccccccc)", "user") usuario.Properties("sAMAccountName").Value = "aaaaaa.bbbbbb.ccccccccc" usuario.Properties("userAccountControl").Value = AdsUserFlags.PasswordNotRequired usuario.Properties("name").Value = "aaaaaa bbbbbbbbbb ccccccccc" usuario.Properties("givenName").Value = "aaaaaa" usuario.Properties("sn").Value = "bbbbbbbbbb ccccccccc" usuario.CommitChanges() End Using End Using </code></pre>

    1. COsAMAccountName is <= 20 characters; userPrincipalName seems to have a much higher limit, but requires `user@domain.local`

    2. COIf the limit is 20 char, why I can create the user using the Active Directory Users and Computers tool?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
