  • This was already discussed here: How to change the sAMAccountName attribute size limit in MIIS?

    In short: no, you can't extend sAMAccountName length.

    Quoting from previous thread:

    you can’t specify in Active Directory a samAccountName with more than 20 characters. The schema definition (256 chars) is overruled by the SAM rules (20 chars).

    This is not a MIIS limitation but an AD restriction.
