0x2077 Illegal modify operation. Some aspect of the modification is not permitted.

I'm trying to import the following LDIF file into an LDS Instance using LDIFDE.

dn: CN=SVCLDAPQuery,CN=Users,DC=testinstance,DC=ADAM
changetype: add
objectClass: user
userPrincipalName: SVCLDAPQuery
userPassword: Passw0rd

Note: For ADAM, Microsoft enabled the userPassword attribute to function as a write-alias for unicodePwd and removed the requirement for the special formatting unicodePwd required. This allows your LDIF files to have clear-text passwords specified.

I am performing the import with the following command:

ldifde -i -f SVCLDAPQuery.ldf -s localhost:10001

This command throws out the following errors:

Connecting to "localhost:10001"
Logging in as current user using SSPI
Importing directory from file "SVCLDAPQuery.ldf"
Loading entries.
Add error on entry starting on line 1: Operations Error
The server side error is: 0x2077 Illegal modify operation. Some aspect of the modification is not permitted.
The extended server error is:
00002077: SvcErr: DSID-033807B5, problem 5012 (DIR_ERROR), data 8237

0 entries modified successfully.
An error has occurred in the program
No log files were written. In order to generate a log file, please
specify the log file path via the -j option.

As the requirement for special formatting of unicodePwd has been lifted Microsoft has placed a default requirement to ensure all password operations are done through LDAPS instead of LDAP. This is why it will not import the password!

To lift this requirement make the following change to the configuration partition of the instance:

Navigate to CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,CN={GUID of the ADAM}

Edit dSHeuristics attribute and set value to 0000000001001

Now you can perform password operations without requiring LDAPS.

  1. You really make it seem so easy with your presentation but I find this matter to be actually something that I think I would never understand.
