Hello,

Communication user get locked due to unsuccessful login attempt.

Reasons:

a) Recently password might be changed for communication user or password expired

b) Communication users details not changed in all RFC communication configuration

You need to check the dev_rfc logs or dev_w? logs to check from where the communication is initiated which is locking the users.

Also check the SM21 for more logs.

Alternate method but not recommended - Change user type to SERVICE this will ensure password is never expire and inturn the users is not locked.

Disadvantage of this user is anyone knowing password can logon using SAPGUI and may create problem.

Hi Rajan,

Thanks for the reply.

Can u plz clarify the following.

a) If the password for the communication user has been expired, then do we need to reset it by using SU01?

b)"Communication users details not changed in all RFC communication configuration"---> I couldnt understand this, so could u plz provide some more information regarding this.

Can we get information in ST05, with related to this problem?

Hi Srinivas,

You will reset it from su01, there might be lot of other RFC's from other systems that might be connecting to the system in question. When you change the password of that communication user, you have to update the communication user credentials for all those RFC's. Your problem is solved once you update the RFC's in sm59.

Hi Srinivas,

Reasons for this:

1) Somebody has changed the password of the communication id

2) An RFC defined to refer that client has an incorrect password in SM59 for that Comm. id.

Passwords for Communication users do not expire. Yes, SU01 is the way by which you change passwords, even for communication users. As mentioned earlier, its a bad idea changing the password of a Comm. user, as all other RFC's referencing to that client will have to be updated with the correct credentials.

Debug the issue more. Look at the change documents of the Comm. user. See if anyone has changed the password. If not, then there might be a possiblity that some RFC referencing to that client has the incorrect details. ST05 is not what you are looking for. Look at SM20N (AIS) for the details.

Do not change Comm. users to Service type! Comm. users normally have broad authorization, making it a service id is a heavy risk as SAP GUI access will be opened up!

You might want to post/move this to the security forum

Thank you
