Hi, When specifying TRUST_DOMAIN In the condor configuration should I consider it a string (quoted) or an _expression_? I thought UID_DOMAIN and TRUST_DOMAIN have to be condor expressions, e.g. the first collector in COLLECTOR_HOST. And in 2018 the GlideinWMS code had to change TRUST_DOMAIN from string to _expression_. But now TRUST_DOMAIN = myhost.domain.org:9618?sock=collectorRANDOM Gives the error 07/10/24 20:14:22 (pid:88014) CONFIGURATION PROBLEM: Failed to insert ClassAd attribute TRUST_DOMAIN = myhost.domain.org:9618?sock=collectorRANDOM. The most common reason for this is that you forgot to quote a string value in the list of attributes being added to the STARTD ad. Thank you, Marco
