  * sos_commands/crypto/fips-mode-setup_--check
    FIPS mode is enabled.

2) Removing parameters "name=p11-kit-proxy" and "library=p11-kit-proxy.so" resolves the error generation in "/var/log/messages" files.

3) If the file "/etc/crypto-policies/local.d/nss-p11-kit.config" is not present then when the below command is run a soft link file is created.

     # fips-mode-setup --enable

     After above command is run  the file "/etc/crypto-policies/back-ends/nss.config" is create as soft link to "/usr/share/crypto-policies/FIPS/nss.txt"
     which does not have the 2 parameter and no error is observed.

   
     - # cat /usr/share/crypto-policies/FIPS/nss.txt

4) As per link [1] it was mentioned that the issue was fixed in IPA 4.8.0 for softHSM but on further review it was only for testing. 
   Please refer PR links [2] and [3]

5) As mentioned in point 2, the error is not observed if the 2 parameter is removed from the file.

    But instead of work around, is there any other method through which we can avoid the error?

Version-Release number of selected component (if applicable):

ipa-server-4.9.2-3.module+el8.4.0+10412+5ecb5b37.x86_64

How reproducible:

Always

Steps to Reproduce:

1. Make sure file "/etc/crypto-policies/local.d/nss-p11-kit.config" is present.

2. Enable FIPS as below.

   # fips-mode-setup --enable
 
3. Reboot the server.

4. Make sure the below is a normal file and has entries entries parameters 
   "name=p11-kit-proxy" and "library=p11-kit-proxy.so" 

   # ls -l /etc/crypto-policies/back-ends/nss.config

   # cat /etc/crypto-policies/back-ends/nss.config

5. Restart IPA service

   # ipactl restart
   # ipactl status

6. Check for the error in "/var/log/messages" file.

   # grep LCK..APIlock /var/log/messages


Actual results:

Error "usr/lib/api/apiutil.c Could not open /run/lock/opencryptoki/LCK..APIlock" is observed for IPA services in "/var/log/messages".

Expected results:

The error should not be observed.

Additional info:

There does not seems to be any impact on IPA performance / operations.
