Increase USER ID size from 12 to 20 at least when running non WIndows IBM MQ Server

See this idea on ideas.ibm.com

Based on this document,

https://www.ibm.com/docs/en/ibm-mq/9.4?topic=application-user-ids

If we use MQ Clients in Windows accessing an IBM MQ running on windows, we can have users ID up to 20 characters. But if the server is not windows, the limit is 12 character.

is there any particular reason for that? If IBM MQ is ready to have longer users, why not when a server is running on non-windows?

We want to move out from IBM MQ running on windows to IBM MQ on Containers using LDAP. We cant not authenticate in LDAP because IBM MQ Server (or i guess in this case the clients) are truncating the user name (sAMAccountName) to 12 characters.

We have several service accounts running around all environments that connect to IBM MQ (currently running on Windows, local users) with more than 12 characters, less than 20. Move to shorter names for all that services accounts (that they are running very importante applications) could cause us many problems.

It seems that clients (MQC, MQ Explorer) are configured to send sAMAccountName to IBM MQ to perform authentication. One solution could be to send another attribute to ibm mq for authentication.

BY example:

sAMAccountName: a-more-than-12-chars

ibmMQname: amt-12-chars

we can not move from IBM MQ Windows to IBM MQ Containers today.
