Hi, i just added the line account required /lib/security/pam_access.so to /etc/pam.d/login to prevent some users from logging into my server. The result was that no user is able to login any more. (error msg: module unknown) In syslog I can read Feb 13 10:06:37 tina login: PAM unable to dlopen(/lib/security/pam_access.so) Feb 13 10:06:37 tina login: PAM [dlerror: /lib/security/pam_access.so: undefined symbol: yp_get_default_domain] Feb 13 10:06:37 tina login: PAM adding faulty module: /lib/security/pam_access.so Feb 13 10:06:38 tina login: Module is unknown after trying to log in. What may be the reason for this behaviour? BTW: /lib/security/pam_access.so exists I'm using a german SuSE 7.3 pro distribution.
