I'm specifically having issues with the following messages in /var/log/secure

Code:
PAM unable to dlopen(/usr/lib64/security/pam_yubico.so): /lib64/libnssutil3.so: undefined symbol: PR_GetEnvSecure
PAM adding faulty module: /usr/lib64/security/pam_yubico.so


I've attempted to update pam_yubico in hopes that would fix the issue but I can't get past configure step since it refuses to recognize that I have all of the required libraries installed. The latest version included in the repo is what we were running prior to updating anything.

Anyone? Anywhere? Thoughts on what to possibly downgrade?

I could upgrade to the newest pam_yubico.so if someone has some thoughts on why configure isn't finding any of the libraries.

Since I'm up against it I figured I'd just keep sharing here, this is the result of configure

Code:
configure: WARNING: libldap not found, will not be compiled (--without-ldap to disable ldap support)
checking for ld used by GCC... /usr/bin/ld -m elf_x86_64
checking if the linker (/usr/bin/ld -m elf_x86_64) is GNU ld... yes
checking for shared library run path origin... done
checking for libykclient... no
configure: error: Libykclient v2.15+ required, see https://developers.yubico.com/yubico-c-client/
[root@host pam_yubico-2.24]# find /* | grep libykclient
/usr/lib64/libykclient.so.3

Hello knobdy,

Have your tried the pam_yubico from epel repo? If not you can follow the instructions linked below to install

yum install epel-release
yum install pam_yubico

https://developers.yubico.com/yubico-pam/

Finally THOUGHT I got all of the dependencies out of the way (that seem pretty ridiculous so far as what - NOT NEW - versions are required) and got to this point...now what?

Code:
Making install in .
make[1]: Entering directory `/tmp/pam_yubico-2.24'

  CC       util.lo

Hello knobdy,

Since you are having issues manually trying to build this, I recommend opening an issue on our GitHub page. This will be reviewed more easily and quickly by our Developers.

Actually, finally figured out how to get the install done "easily".

I've reverted back to the original working system.
I've installed the latest version of pam_yubico.
I've updated the system.
Same errors:
Code:
Mar 28 18:37:24 host cw: PAM unable to dlopen(/usr/lib64/security/pam_yubico.so): /lib64/libnssutil3.so: undefined symbol: PR_GetEnvSecure
Mar 28 18:37:24 host cw: PAM adding faulty module: /usr/lib64/security/pam_yubico.so


I'll hop on GitHub just the same...

Matthew,

Yes, that's what I'm using now - same issue, all versions I can find of the RPM. I reached out on GitHub and so far the best they can do is suggest ABI incompatibilities. I'm not sure how to troubleshoot those - and this is the only PAM module complaining.
