MQAUSX and Microsoft Active Directory
Centralize authentication is a great thing. Many customers use MQAUSX on AIX, HP-UX, IBM i (OS/400), Linux, Solaris and authenticate against Microsoft Active Directory (AD) as a remote LDAP server. Since, AD conforms to LDAP v3, this generally works very well. Some companies configure their AD servers such that the attribute sAMAccountName contains the user’s […]

Where’s the MQ Security?
I was at Wendy’s (in Canada) for lunch today and the cashier put the following flyer on my tray: Of course, it made me smile because I recently wrote a blog item that MQ people still need to implement either SSL or a security exit in WMQ v7.1. Maybe, I should create some T-Shirts with […]

MQAUSX LDAP on Linux x86 & Linux x64
When MQAUSX first supported LDAP authentication, Capitalware used Novell’s LDAP Libraries for C for AIX, HP-UX, Solaris, Linux x86, Linux x64 (x86 64-bit) and Windows. Several years ago, for AIX, HP-UX and Solaris platforms, we switched to the native/included client LDAP libraries that are available for each OS (Operating System). This week, a weird bug […]

MQAUSX/MQSSX versus WMQ v7.1 CHLAUTH
Last week, there was a robust/lively discussion on the MQSeries List Server regarding Derek Hornby’s question of (see http://comments.gmane.org/gmane.network.mq.devel/13985): In the MQ V7.1 base install, a channel authentication record is created which is a “block user list” for all channels, and the block is on a User List of *MQADMIN So I created a User […]

Where’s the Security?
Over the last 2 months, all of the sudden, I have “where’s the security?” phrase running through my head. Instead of that little old lady from the 80’s Wendy’s commercial saying “Where’s the beef?”, I have her in my head saying “Where’s the security?”. Back in 2005, when I first starting selling Capitalware’s MQ Authenticate […]

WebSphere MQ v7.1 and MQAUSX
Capitalware has begun testing MQAUSX with WebSphere MQ (WMQ) v7.1 and everything is working very well. There are 2 items that everyone needs to be aware of when using MQAUSX with WMQ v7.1. 1. WMQ v7.1 has a new feature called Channel Authentication Records. (A poor name as no authentication is actually taking place. IBM […]

MQAUSX without a Client-side Security Exit – Part 2
As mentioned in Part 1, I often get asked if MQAUSX can authenticate a UserID and Password without the requirement of a client-side security exit. The answer is yes. Part 1 demonstrated how to set a UserID and Password for a client connection to a remote queue manager via code samples (i.e. C, C++, C#, […]

MQAUSX without a Client-side Security Exit – Part 1
Quite often I get asked if MQAUSX can authenticate a UserID and Password without the requirement of a client-side security exit. The answer is yes. MQAUSX is actually 3 products in one: 1. If the client application is configured with the client-side security exit then the user credentials are encrypted and sent across the wire […]

Capitalware products and HP-UX on Itanium (IA64)
For the record, Capitalware will support all of its commercial and open source products on HP’s HP-UX for Itanium (IA64) for as long as customers require it. By no means am I taking sides in the HP/Oracle war, I’m just stating what Capitalware’s support position is. If you want to read about the HP/Oracle Itanium […]

MQAUSX and AES 256-bit Encryption
MQ Authenticate User Security Exit (MQAUSX) currently uses the ‘Tiny Encryption Algorithm Variant’ (aka TEAV or XTEA) for encryption and decryption of the user’s password between the client-side security exit and the server-side security exit. The security group of existing customers and potential customers are requesting that we use Advanced Encryption Standard (AES) symmetric-key encryption […]
